Comparative effectiveness data of COVID-19 vaccines remain limited. We conducted a systematic review and network meta-analysis (NMA) feasibility assessment of effectiveness studies of Omicron-adapted COVID-19 vaccines.

Searches in MEDLINE and Embase up to February 2025 identified studies comparing the effectiveness of Omicron-adapted COVID-19 vaccines, either directly or against no recent vaccine. Two investigators independently selected articles reporting adjusted vaccine effectiveness (VE). A feasibility assessment determined the appropriateness of a common comparator and evaluated effect modifiers (EMs). Data extraction and risk-of-bias assessment were performed by one investigator and validated by a second investigator. Bayesian NMAs using random-effects models were performed for base-case analyses, data permitting.

The review identified 25 studies for Omicron-adapted COVID-19 vaccines: 16 for XBB formulations, eight of which were included in NMAs, all for mRNA formulations, representing 29.9 million participants. BNT162b2 had the largest evidence base. Comparisons between XBB.1.5-adapted BNT162b2 (Comirnaty) and mRNA-1273 (Spikevax) found that both vaccines are effective and comparable against XBB-related hospitalizations, infections, and medically attended visits in adults Among elderly, the estimated effectiveness against XBB-related hospitalizations favored BNT162b2.

Findings of this NMA of observational studies support the effectiveness of XBB.1.5-adapted mRNA vaccines. Limitations included assumptions on EMs and sparse evidence networks.

This systematic review with network meta-analysis (NMA) analysed the current evidence on in vitro studies comparing trueness of fit, surface roughness, colour stability, surface wettability, water sorption, water solubility, and microbial adhesion between conventional and digital denture bases.

From inception until December 2023, a systematic search of published in-vitro studies from Scopus, PubMed, and the Cochrane Central Register of Controlled Studies was conducted. The protocol was registered in PROSPERO (CRD42024531416). NMA compared properties related to dimensional accuracy and surface properties between conventional and digital dentures. The ranking was performed using the surface area under the cumulative ranking guidelines.

A total of 6004 articles were initially identified, of which 342 duplicates were removed, and 5566 were excluded by screening the titles and abstracts. A total of 96 articles were assessed by full-text reading, and 43 were included in the quantitative synthesis. As per the NMA results, MIL demonstrated significantly higher trueness of fit when compared with conventional compression moulding (standardized mean differences [SMD] = -2.25 [95% CI: -4.09, -0.40]), P = .017 (<.05) and TDP (SMD = -1.57 [95%CI: -3.14, -0.01]) P < .05. MIL demonstrated significantly lower surface roughness when compared with conventional compression moulding (SMD = -0.99 [95% CI: -1.72, -0.26]), P = .008 (<.05), and TDP (SMD = -1.08 [95%CI: -1.95, -0.22]) P < .05.

There is conclusive evidence that milled digital denture bases demonstrate higher trueness of fit and lower surface roughness than 3D-printed denture bases and conventional denture bases, as demonstrated by the concurrent network and pairwise results.

In vitro studies show that milled digital dentures exhibit higher accuracy and lower surface roughness. The clinical performance of milled dentures in relation to these properties needs to be evaluated by high-quality randomized controlled clinical trials.

Individuals with autism spectrum disorder (ASD) exhibit a wide variety of symptoms related to social interaction and behaviour. Atypical antipsychotics have been widely evaluated and prescribed to treat distressing symptoms (e.g. irritability, aggression, obsessions, repetitive behaviours, etc.) in children and adults with ASD. Still, their effects and relative efficacy remain unclear.

Primary: to assess the comparative benefits of atypical antipsychotics for irritability through network meta-analyses in children and adults with ASD at short-term follow-up. Secondary: to assess the benefits and harms of atypical antipsychotics, compared to placebo or any other atypical antipsychotic, for different symptoms (e.g. aggression, obsessive-compulsive behaviours, inappropriate speech) and side effects (e.g. extrapyramidal symptoms, weight gain, metabolic side effects) in children and adults with ASD at short-, medium- and long-term follow-up.

We searched CENTRAL, MEDLINE, 10 other databases, and two trial registers, together with reference checking, citation searching and contact with study authors to identify studies for inclusion. The latest search was 3 January 2024.

Randomised controlled trials (RCTs) comparing any atypical antipsychotic drug with placebo or another atypical antipsychotic drug for adults and children with a clinical diagnosis of ASD.

Critical outcomes included irritability, aggression, weight gain, extrapyramidal side effects, obsessive-compulsive behaviours and inappropriate speech.

We used the Cochrane RoB 2 tool to assess risk of bias in the included studies.

We performed statistical analyses using a frequentist network meta-analysis for combined estimates for the outcome irritability and a random-effects model for pairwise comparisons for other outcomes. We rated the certainty of the evidence using GRADE.

We included 17 studies with 1027 randomised participants. One study evaluated adults (31 participants); the remaining 16 studies evaluated children (996 participants). The interventions were risperidone, aripiprazole, lurasidone and olanzapine.

Comparative efficacy on irritability Based on the network meta-analysis, risperidone and aripiprazole may reduce symptoms of irritability compared to placebo in the short term in children with ASD (risperidone: mean difference (MD) -7.89, 95% confidence interval (CI) -9.37 to -6.42; 13 studies, 906 participants; low-certainty evidence; aripiprazole: MD -6.26, 95% CI -7.62 to -4.91; 13 studies, 906 participants; low-certainty evidence). Lurasidone probably results in little to no difference in irritability compared to placebo in the short term (MD -1.30, 95% CI -5.46 to 2.86; 13 studies, 906 participants; moderate-certainty evidence). Efficacy and safety on other outcomes We are very uncertain about the effects of atypical antipsychotics on aggression compared to placebo at short-term follow-up in children with ASD (risk ratio (RR) 1.06, 95% CI 0.96 to 1.17; 1 study, 66 participants; very low-certainty evidence). The certainty of the evidence was very low due to concerns about risk of bias and serious imprecision. We are very uncertain about the effects of atypical antipsychotics on the occurrence of weight gain (above predefined levels) compared to placebo in the short term in children with ASD (RR 2.40, 95% CI 1.25 to 4.60; 7 studies, 434 participants; very low-certainty evidence). We are also very uncertain about the effects of atypical antipsychotics on weight gain (in kilograms) compared to placebo in the short term in children with ASD (MD 1.22 kg, 95% CI 0.55 to 1.88; 3 studies, 297 participants; very low-certainty evidence). In both, the certainty of the evidence was very low due to concerns about risk of bias and serious imprecision. We are very uncertain about the effects of atypical antipsychotics on the occurrence of extrapyramidal side effects compared to placebo in the short term in children with ASD (RR 2.36, 95% CI 1.22 to 4.59; 6 studies, 511 participants; very low-certainty evidence). The certainty of the evidence was very low due to concerns about risk of bias and serious imprecision. Atypical antipsychotics may improve obsessive-compulsive behaviours compared to placebo in the short term in children with ASD (MD -1.36, 95% CI -2.45 to -0.27; 5 studies, 467 participants; low-certainty evidence). The certainty of the evidence was low due to concerns about risk of bias and heterogeneity. Atypical antipsychotics may reduce inappropriate speech compared to placebo in the short term in children with ASD (MD -1.44, 95% CI -2.11 to -0.77; 8 studies, 676 participants; low-certainty evidence). The certainty of the evidence was low due to concerns about risk of bias and heterogeneity. We were unable to evaluate the effects of other atypical antipsychotics. Furthermore, our findings on adults with autism were scarce due to the lack of available studies.

Risperidone and aripiprazole may reduce symptoms of irritability compared to placebo in children with ASD in the short term, but lurasidone probably has little to no effect on irritability compared to placebo. Other benefits and potential harms observed ranged from moderate- to very low-certainty evidence. The available data did not allow comprehensive subgroup analyses. New randomised controlled trials with larger sample sizes are needed to balance the efficacy and safety of interventions with enough certainty, which are currently scarce (or even absent in the case of the adult population). Authors should report population and intervention characteristics transparently, providing disaggregated or individual patient data when possible. Furthermore, consistent measurement methods for each outcome should be reported to avoid problems during the data synthesis process.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To compare, via a network meta-analysis, the effectiveness and safety of different immunotherapy agents that are administered in a perioperative setting to people with resectable non small-cell lung cancer To perform indirect comparisons in order to generate a clinically meaningful hierarchy of perioperative strategies of immunotherapy administration for overall survival in operable people with resectable non small-cell lung cancer.

Graves orbitopathy is a specialized immunoinflammatory disorder related to abnormal thyroid function. Due to the complexity of the disease and its propensity to reoccur, targeted treatment is essential to improve the symptoms.

This study aims to assess the efficacy and safety of various treatments for active thyroid eye disease.

We conducted a comprehensive search for randomized controlled trials (RCTs), and ongoing RCTs registered on Controlled Trials, targeting treatments for thyroid eye disease until November 20, 2024. Employing a Bayesian framework, this network meta-analysis calculated risk ratios (RRs) or mean differences (MDs) with 95% CIs to size the effects for the predetermined outcomes. The study is registered with PROSPERO (CRD42024548030).

The primary outcomes evaluated were overall response rate, clinical activity score (CAS), proptosis, diplopia, and adverse events.

For the overall response rate, teprotumumab (RR 5.5, 95% CI 2.3 to 16), mycophenolate combined intravenous glucocorticosteroids (IVGCs) demonstrated effectiveness over no treatment, ranked from most to least effective. Notably, teprotumumab showed the highest efficacy in reducing CAS (MD -1.57, 95% CI -3.81 to 0.68) and proptosis (MD -2.29, 95% CI -2.73 to -1.86). For diplopia improvement, teprotumumab and IVGCs were effective compared with no treatment.

Teprotumumab emerges as potentially the most effective treatment for reducing inflammation and increasing overall response rates when compared with no treatment; oral mycophenolate combined with IVGCs appears to be the best for improving proptosis. While some treatments raise safety concerns due to reported adverse events, oral methotrexate combined with IVGCs appear to offer a favorable balance between efficacy and safety among the evaluated treatments.

Pneumocystis jirovecii pneumonia (PCP) is a serious opportunistic infection in people living with HIV (PWH) who have low CD4 counts. Despite its side effects, trimethoprim-sulfamethoxazole (TMP-SMX) is currently considered the primary treatment for PCP.

The objectives of this study are to compare the efficacy (treatment failure and mortality) and tolerability (treatment change) of PCP treatment regimens with a frequentist network meta-analysis.

Data sources include Embase, Medline, and CENTRAL from inception to 3 February 2024.

Study eligibility criteria include comparative randomized controlled trials (RCTs) of at least two PCP treatment regimens.

Participants include PWH.

Interventions include treatment regimens for PCP compared head-to-head.

Assessment of risk of bias includes Cochrane Risk-of-bias tool for RCTs (Cochrane Risk-of-Bias 2).

Title, abstract, and full-text screening, along with data extraction, were conducted by two independent reviewers. Data on PCP treatment failure, all-cause mortality, and discontinuation because of toxicity were pooled and ranked.

Fourteen RCTs conducted between 1983 and 1996 included 1788 participants across 27 treatment arms. No regimen showed statistically significant superiority over TMP-SMX in direct comparison. In the network meta-analysis, clindamycin/primaquine was ranked the best (surface under the cumulative ranking curve, 0.8), followed by intravenous pentamidine (0.8) and TMP-SMX (0.8) regarding treatment failure. Regarding all-cause mortality, TMP-SMX was superior to atovaquone in direct comparison, but no treatment was superior in the full network analysis. Dapsone-TMP (0.7) and intravenous pentamidine (0.8) were ranked the highest for mortality reduction. For safety and tolerability, comparator drugs consistently outperformed TMP-SMX, with significant reductions in toxicity observed for dapsone-TMP, inhaled pentamidine, and atovaquone. Inhaled pentamidine (0.9) was the best tolerated, followed by trimetrexate (0.8) and atovaquone (0.8).

We conclude that TMP-SMX should be reassessed as the standalone first-line therapy for PCP in PWH, given the better tolerability and comparable efficacy of other treatments. In places with access to alternative drugs for PCP treatment, our analysis suggests that alternative regimens may offer comparable effectiveness, providing flexibility to use alternative treatments when comorbidities necessitate it.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: Primary objective To evaluate the relative benefits and harms of therapy with glucagon-like peptide-1 receptor agonists (GLP-1RA), sodium-glucose co-transporter-2 inhibitors (SGLT2i), and their combination in adults with type 2 diabetes mellitus. Secondary objectives To determine the relative rankings of GLP-1RA, SGLT2i, and their combination, according to their comparative efficacy for the critical outcomes identified in this review through a network meta-analysis.

Postpartum haemorrhage (PPH) is the leading cause of maternal mortality worldwide. Prophylactic uterotonic agents can prevent PPH. The current World Health Organization (WHO) recommendation for preventing PPH is 10 IU (international units) of intramuscular or intravenous oxytocin. Several uterotonics prevent PPH, but there remains uncertainty about the most effective agent with the fewest side effects. This is an update of a review first published in April 2018, and incorporates trustworthiness screening of eligible trials.

To identify the most effective uterotonic agent(s) to prevent PPH with the fewest side effects, and generate a ranking according to their effectiveness and side effect profile.

On 5 February 2024, we searched CENTRAL, MEDLINE, Embase and CINAHL in collaboration with the Cochrane Information Specialist.

All randomised controlled trials (RCTs) or cluster-RCTs that compared the effectiveness and side effects of uterotonic agents with other uterotonic agents, placebo or no treatment for preventing PPH were eligible for inclusion. We screened eligible trials for trustworthiness. We included randomised trials published only as abstracts if we could retrieve sufficient information; we excluded quasi-randomised trials.

Primary outcomes were PPH ≥ 500 mL and PPH ≥ 1000 mL. Secondary outcomes included use of additional uterotonics, blood transfusion, vomiting, hypertension, and fever.

We used RoB 1 to assess risk of bias.

At least three review authors independently assessed trials for inclusion, trustworthiness, risk of bias, and certainty of evidence using GRADE. We estimated the relative effects and rankings for the primary and secondary outcomes. We reported primary outcomes for prespecified subgroups, stratified by mode of birth (caesarean versus vaginal), setting (hospital versus community), prior risk of PPH (high versus low), dose of misoprostol (≥ 600 μg versus < 600 μg), and regimen of oxytocin (bolus versus bolus plus infusion versus infusion only). We performed pairwise meta-analyses and network meta-analysis to determine the relative effects and rankings of all available agents.

The network meta-analysis included 122 trials (121,931 women), involving seven uterotonic agents and placebo or no treatment, conducted across 48 high-, middle- and low-income countries. Most were in a hospital setting (115/122, 94%), with women having a vaginal birth (87/122, 71%).

Relative effects from the network meta-analysis suggested that all agents, except injectable prostaglandins, for which data were limited, were effective for preventing PPH ≥ 500 mL compared with placebo or no treatment. The two highest-ranked agents were ergometrine plus oxytocin and misoprostol plus oxytocin. Compared with oxytocin, ergometrine plus oxytocin reduces PPH ≥ 500 mL (risk ratio (RR) 0.76, 95% confidence interval (CI) 0.64 to 0.90, high-certainty evidence), and misoprostol plus oxytocin probably reduces PPH ≥ 500 mL (RR 0.70, 95% CI 0.57 to 0.87; moderate-certainty evidence). Carbetocin (high-), injectable prostaglandins (moderate-) and ergometrine (low-certainty evidence) have similar effects compared with oxytocin. The evidence for misoprostol is very low certainty. All agents, except ergometrine and injectable prostaglandins, for which data were limited, were effective for preventing PPH ≥ 1000 mL compared with placebo or no treatment. Ergometrine plus oxytocin, and misoprostol plus oxytocin were the highest-ranked agents. Compared with oxytocin, carbetocin and injectable prostaglandins (both moderate-certainty evidence), and misoprostol plus oxytocin (low-certainty evidence) make little or no difference to PPH ≥ 1000 mL. Misoprostol may be less effective in preventing PPH ≥ 1000 mL compared with oxytocin (RR 1.24, 95% CI 1.06 to 1.46; low-certainty evidence). The certainty of evidence for ergometrine and ergometrine plus oxytocin was very low. Compared with oxytocin, misoprostol plus oxytocin probably reduces the use of additional uterotonics (RR 0.55, 95% CI 0.42 to 0.72, moderate-certainty evidence), and carbetocin (RR 0.74, 95% CI 0.59 to 0.94; low-certainty evidence), and ergometrine plus oxytocin may reduce the use of additional uterotonics (RR 0.68, 95% CI 0.56 to 0.83; low-certainty evidence). Misoprostol (low-certainty evidence) makes little or no difference to this outcome. Misoprostol plus oxytocin probably reduces the risk of needing a blood transfusion (RR 0.40, 95% CI 0.28 to 0.58; moderate-certainty-evidence), and ergometrine plus oxytocin may reduce the risk of blood transfusion compared with oxytocin (RR 0.73, 95% CI 0.56 to 0.96, low-certainty evidence). Carbetocin (moderate-certainty evidence) and misoprostol (low-certainty evidence) probably make little or no difference to this outcome compared with oxytocin. All uterotonic agents, except for carbetocin, were associated with increased risks of side effects compared with oxytocin. Misoprostol may increase the likelihood of nausea, vomiting and fever, and probably increases the risk of diarrhoea. Injectable prostaglandins may increase the likelihood of diarrhoea. Ergometrine probably increases the likelihood of nausea and vomiting, and may increase the likelihood of hypertension, headache, and diarrhoea. Ergometrine plus oxytocin may increase the likelihood of nausea, vomiting, and diarrhoea. Misoprostol plus oxytocin probably increases the likelihood of nausea, vomiting and diarrhoea, and may increase the likelihood of fever. Analyses of the prespecified subgroups did not reveal important subgroup differences. Evidence for outcomes not presented above but reported in the summary of findings tables was very low certainty.

Most agents are effective for preventing PPH when compared with placebo or no treatment. Ergometrine plus oxytocin, and misoprostol plus oxytocin may be more effective than the current standard oxytocin. All agents, except for carbetocin, are associated with an increased risk of some side effects compared with oxytocin.

Cochrane Library; Registration number: CD011689 and protocol [and previous versions] available via DOI: 10.1002/14651858.CD011689 [DOI: 10.1002/14651858.CD011689.pub3 and DOI: 10.1002/14651858.CD011689.pub2].

This study aims to identify patient subgroups who benefit more from perioperative immunotherapy combined with chemotherapy (IO-CT) based on clinical and molecular characteristics in resectable non-small cell lung cancer (NSCLC).

Randomized controlled trials (RCTs) on perioperative IO-CT were searched. Beneficial differences of IO-CT regimens across different patient subgroups were assessed by pooling trial-specific ratios in event-free survival (EFS), overall survival (OS), pathological complete response (pCR), and major pathological response (MPR).

Six studies (n = 3003) involving five IO-CT regimens were included. Compared to CT alone, all IO-CT regimens significantly improved EFS, OS, MPR, and pCR, but increased toxicity. Toripa-chemo showed the best EFS and nivo-chemo showed the best OS. Patients with PD-L1 ≥ 1% had more EFS benefits compared to those with PD-L1 < 1% (HR [hazard ratio]: 1.55, 95% CI 1.17-2.04). Squamous NSCLC patients had significantly more pCR and MPR benefits than non-squamous NSCLC patients (pCR: OR [odds ratio] 0.68, 95% CI 0.49-0.95; MPR: OR 0.61, 95% CI 0.45-0.82). Former smokers had significantly higher pCR benefits than non-smokers (OR: 2.18; 95% CI 1.21-3.92). Additionally, OS benefit was significantly higher in patients < 65 years compared to those ≥ 65 years (HR ratio: 0.59, 95% CI 0.36-0.95). For MPR, males benefited significantly more from IO-CT compared to females (OR: 1.69, 95% CI 1.18-2.42).

Perioperative IO-CT is more effective but more toxic than CT alone in resectable NSCLC. Patients with PD-L1 ≥ 1%, squamous NSCLC, a history of smoking, age < 65 years and male gender may experience greater benefits from perioperative IO-CT.

An increasing number of patients with rectal cancer who respond well to neoadjuvant chemoradiotherapy (nCRT) are being considered for organ preservation programs. However, due to the lack of high-level evidence, the survival outcomes of the organ preservation programs are still full of controversy and uncertainty.

To assess the effects of total mesorectal excision (TME) surgery, watch-and-wait (W&W), and local excision (LE) on long-term outcomes after nCRT, we searched PubMed, Embase, and Web of Science for articles published between 1 January 2010, and 31 December 2023.

We found 7029 pieces of literature, of which 26 studies met the inclusion criteria, and recruited 2778 participants in the network meta-analysis. Risk of bias assessment showed that most included studies had a low risk of bias. Low-certainty evidence suggests that the TME group was significantly superior to all other interventions for the 2-year local regrowth rate. (W&W group [OR, 0.20; 95% CI, 0.12-0.35], LE group compared with TME group [3.00; 1.60-5.80]). There was no significant difference in the 2-year local regrowth rate between W&W and LE group (OR, 0.60; 95% CI, 0.32-1.20). There was high to moderate certainty evidence that at 3 years, the W&W group had a significant advantage in overall survival compared with the TME group (OR, 0.37; 95% CI, 0.09-0.95). After 5 years, no significant difference in overall survival was found between the 3 treatment modalities.

We concluded that TME achieved the most significant reduction in 2-year local regrowth rates. However, the W&W strategy and LE demonstrated noninferiority to TME in long-term survival outcomes.

Pre-fabricated fibre posts facilitate post-endodontic restoration of endodontically treated teeth with insufficient coronal tooth structure. Recent advancements in digital dentistry have led to the introduction of custom-made fibre posts fabricated with computer-aided design-computer-aided manufactured (CAD-CAM) technology. However, evidence on the comparative performance of the different post-types is lacking. This systematic review with network meta-analysis aimed to analyse the current evidence on in-vitro studies comparing bond strength, catastrophic failures, fracture resistance, and cement film thickness between CAD-CAM fibre posts and other post types, including pre-fabricated fibre and custom-made cast-metal posts.

A systematic search was conducted in PubMed, Scopus, and the Cochrane Central Register of Controlled Studies for in-vitro studies from inception until December 2023 (PROSPERO: CRD42024501614). Network meta-analysis and pairwise meta-analysis were performed. The ranking was performed using the surface area under the cumulative ranking (SUCRA) guidelines.

Seven hundred forty-one articles were identified, of which 80 duplicates were removed, and 585 were excluded by screening the titles and abstracts. A total of 76 articles were assessed by full-text reading, and 16 were included in the quantitative synthesis. CAD-CAM fibre posts (SMD = 1.09 [95% CI: 0.01, 2.17]) P = 0.04 demonstrated higher bond strength when compared to pre-fabricated posts. CAD-CAM fibre posts (RR = 0.39 [95% CI: 0.23, 0.69]) P < 0.05 demonstrated a lower risk for catastrophic failures when compared to pre-fabricated fibre posts.

In-vitro studies demonstrated that CAD-CAM fibre posts demonstrated higher bond strength, lower catastrophic failure rates, and similar fracture resistance compared to pre-fabricated and cast metal posts. The data on bond strength and catastrophic failures of CAD-CAM fibre posts must be validated clinically by high-quality, randomised, controlled clinical trials.

The goal of on-demand treatment for hereditary angioedema attacks is to halt attack progression to minimize morbidity and mortality. Four on-demand treatments have been approved thus far (ecallantide, icatibant, recombinant human C1 esterase inhibitor [rhC1INH], and plasma-derived C1INH). Results from the sebetralstat phase 3 KONFIDENT trial (NCT05259917) have been reported. To put these results into context without head-to-head trials, an indirect treatment comparison (ITC) was conducted to facilitate comparisons of efficacy and safety across treatment options.

Based on a systematic literature review and feasibility assessment, only the pivotal trial for intravenous rhC1INH (NCT01188564) reported necessary data for a comparable primary efficacy endpoint (time to beginning of symptom relief) to enable an ITC with oral sebetralstat. Bayesian fixed-effects network meta-analyses models were conducted to indirectly compare the efficacy and safety outcomes of sebetralstat and rhC1INH (NCT01188564, NCT00225147, NCT00262301). A matching-adjusted indirect comparison (MAIC) of efficacy was performed, adjusting for baseline attack severity and demographic characteristics.

The fixed-effects model found no significant differences in time to beginning of symptom relief between sebetralstat 300 mg and rhC1INH 50 IU/kg (hazard ratio [95% credible interval], 0.96 [0.42-2.15] to 1.19 [0.58-2.45]). After adjusting for baseline attack severity, the MAIC showed numerically favorable results with sebetralstat compared with rhC1INH, regardless of whether baseline demographics were matched. The fixed-effects model found no significant differences in treatment-related treatment-emergent adverse events. All sensitivity analyses returned consistent results.

This ITC found no significant differences in time to beginning of symptom relief and overall treatment-related treatment-emergent adverse events between sebetralstat and rhC1INH.

The study aimed to conduct a network meta-analysis of randomized controlled trials (RCTs) to examine the effectiveness and safety of traditional Chinese patent medicine (TCPM), either used alone or combined with conventional treatment (CT) of chemical drugs, for treating chronic atrophic gastritis (CAG).

We searched the literature from database creation to December 2023; our primary endpoint was clinical response rate. Secondary outcome measures were the inhibition rate of Helicobacter pylori and clinical symptom score, including pain and noisy scores for the stomach, score for belch and acid reflux, score for the bitter taste and the dry throat, and safety according to total adverse events. Data analyzed using RevMan 5.3, R (v4.0.2), and Stata SE 15.0. Mean differences (MDs) for continuous outcomes and odds ratios (ORs) for dichotomous outcomes and drug ranking by P-score. Network meta-analysis presented as forest plot and league table. Results reported as MDs/ORs with 95% confidence interval (CI).

Our analysis comprised 49 RCTs with 5218 patients. Compared to using CT alone, all TCPMs + CT performed better in improving clinical response rate. The Weifuchun tablet (WFCT) inhibition rate (OR = 9.05; 95% CI = 1.89-43.34; P-score = .92) was relatively high, but only 1 RCT supported this result. WFCT + CT (OR = 2.94; 95% CI = 1.97-4.39; P-score = .57), Qizhiweitong granule (QZWTG) + CT (OR = 2.91; 95% CI = 1.07-7.89; P-score = .55), and Moluodan (MLD) + CT (OR = 2.44; 95% CI = 1.37-4.36; P-score = .43) had certain advantages in inhibiting H pylori compared to using CT alone. Compared with CT, Weisu tablet (WST) + CT (OR = 0.21; 95% CI = 0.05-0.89; P-score = .24) and Xiangshayangwei pill (XSYWP) + CT (OR = 0.41; 95% CI = 0.18-0.92; P-score = .44) were drugs that were less likely to cause adverse reactions.

Our results demonstrate that, compared to using CT alone, TCPMs combined with CT can improve the clinical response rate in the treatment of CAG. Additionally, some TCPMs combined with CT can enhance the H pylori inhibition rate. WST + CT and XSYWP + CT can even reduce the occurrence of adverse reactions.

What interventions effectively prevent postoperative stenosis following endoscopic resection (ER) of superficial esophageal cancer? This study aimed to identify effective interventions or combinations through a systematic review and network meta-analysis.

Six databases were systematically searched for eligible studies up to 30 April 2023, on interventions to prevent esophageal stenosis post-ER. Odds ratios (ORs) evaluated stenosis rate (primary outcome) and complications (secondary outcome), while mean differences (MD) evaluated endoscopic balloon dilatation (EBD) sessions post-stenosis.

Twenty-three studies involving 1271 patients and 11 different interventions were included. Eight interventions were effective in preventing post-ER stenosis: oral hydrocortisone sodium succinate and aluminum phosphate gel (OHA) (OR: 0.02, 95% credible interval [CrI]: 0.00-0.11), polyglycolic acid (PGA) + ST (OR: 0.02, 95% CrI: 0.00-0.23), oral tranilast (OT) + preemptive endoscopic balloon dilatation (PEBD) (OR: 0.08, 95% CrI: 0.01-0.77), botulinum toxin (BT) (OR: 0.10, 95% CrI: 0.03-0.32), ST (OR: 0.08, 95% CrI: 0.01-0.67), oral steroid (OS) (OR: 0.11, 95% CrI: 0.05-0.28), endoscopic triamcinolone injection (ETI) + OS (OR: 0.17, 95% CrI: 0.07-0.42), and ETI (OR: 0.18, 95% CrI: 0.11-0.30). Five interventions significantly reduced EBD sessions: PGA + ST (MD: -5.78, 95% CrI: -11.04 to -1.21), ETI + OS (MD: -3.27, 95% CrI: -5.37 to -0.72), OS (MD: -6.18, 95% CrI: -9.43 to -3.38), ETI (MD: -3.81, 95% CrI: -5.74 to -1.99), and BT (MD: -2.16, 95% CrI: -4.12 to -0.40). None of the interventions significantly increased complications.

This study confirmed the efficacy of OS, ETI, and ETI + OS and verified five other interventions (OHA, PGA + ST, OT + PEBD, BT, and ST) in preventing stenosis. Notably, PGA + ST and BT also reduced the number of EBD sessions.

The efficacy of insulin self-titration in type 2 diabetes (T2D) varies by support strategy. This study aimed to identify the effects of different insulin self-titration support strategies in patients with T2D.

PubMed, EMBASE, CENTRAL, and EBSCO Open Dissertations were searched from inception to January 2023. Randomized controlled trials (RCTs) on T2D patients that reported HbA1c reduction of insulin self-titration supports were included. The interventions were classified based on the following components: dosage guidance (DG), non-dosage guidance (NDG) and empowerment. The pooled estimates were presented as mean differences (MDs) and risk ratios (RRs) with 95 % confidence interval (CI) using a random-effects model. The certainty of evidence was evaluated utilizing the CINeMA online platform.

Seventeen RCTs (13,528 participants) were included. Compared with usual care (UC), the greatest reduction in HbA1c was observed in patients receiving dosage guidance/Empowerment (MD -1.20; 95 %CI: -2.33,-0.07), with moderate certainty of evidence. Lesser HbA1c reduction, MD [95 % CI], were observed in other support strategies when compared with usual care as follows: -0.97 [-1.24,-0.69] in non-dosage guidance/Empowerment, -0.42 [-0.60,-0.24] in dosage guidance, and -0.31 [-0.58,-0.03] in non-dosage guidance. The risk of severe hypoglycemia was not significantly difference among all support strategies, with very low certainty.

Incorporating patient empowerment into insulin self-titration support strategy, either dosage or non-dosage guidance, is more effective in lowering HbA1c.

Post-traumatic stress disorder (PTSD) is a potentially disabling condition that can lead to long-term impairments, with a significant proportion of adolescents being affected by trauma. Studies have suggested that trauma-focused cognitive behavioral therapy (TF-CBT) is an effective treatment for PTSD in adolescents, however, little is known about the relative advantages of different mind-body interventions. The network meta-analysis aims to evaluate and compare the efficacy of various mind-body interventions in alleviating PTSD symptoms in adolescents.

A systematic search was conducted across multiple databases including PubMed, Embase, Web of Science, Scopus, The Cochrane Library, CNKI, WFDSP, and VIP databases. Randomized controlled trials (RCTs) evaluating the effects of mind-body interventions on PTSD in adolescents were included. A network meta-analysis (NMA) was conducted to evaluate the effectiveness of various mind-body intervention therapies using the Surface Under the Cumulative Ranking curve (SUCRA). SUCRA calculates the mean of the cumulative percent area under the curve for each therapy, providing a comprehensive ranking of treatment efficacy. The primary outcomes measured were changes in PTSD symptom scores post-treatment and at follow-ups ranging from 1 to 12 months.

A total of 20 studies involving 5 interventions and 2085 adolescents were included in the analysis. No inconsistencies were found between direct and indirect evidence. TF-CBT consistently demonstrated the most significant effect in reducing PTSD symptoms compared to routine care and no-treatment groups. The ranking of intervention efficacy from highest to lowest was as follows: TF-CBT (SUCRA = 87.3%), meditation, CBT, yoga combined with meditation and mindfulness (SUCRA = 32.3%). Due to limited evidence, the follow-up results for PTSD symptom changes remained inconclusive.

Five mind-body interventions were found to be effective in treating PTSD symptoms in adolescents, with TF-CBT emerging as the most effective treatment. Findings suggest that yoga combined with meditation and mindfulness may have promising effects, however, further research is needed to confirm these results due to the limited evidence available.

Patients undergoing lower-limb orthopedic surgery may experience multiple postoperative complications. Although peripheral nerve stimulation (PNS) is a promising non-pharmacological approach that has been used in lower-limb postoperative recovery, the clinical efficacy of PNS remains inconclusive. This study systematically searched three databases (PubMed, Embase, and Cochrane Library) for randomized controlled trials (RCTs) that examined the treatment effects of PNSs in patients who underwent lower-limb orthopedic surgery up to September 29, 2023. Two investigators independently identified studies, extracted data, and conducted meta-analyses with Review Manager 5.4. The outcomes were pain relief (measured by reductions in pain intensity and analgesic consumption) and functional improvements (range of motion [ROM] and length of hospitalization [LOH]). A total of 633 patients including 321 in the experimental groups and 312 in the control groups from eight RCTs were included. PNS showed no significant effect on pain intensity, while analgesic consumption was marginally significantly reduced in the experimental group. Furthermore, no significant differences were observed regarding functional improvements in ROM or LOH after the intervention. Although PNS had no significant effect on pain relief or functional improvements, the intervention exhibited a marginally significant reduction in analgesic consumption. Future trials should be conducted with larger sample sizes, longer follow-up periods, and more varied stimulation parameters.

This study compared the relative efficacy of first-line lenvatinib, a standard-of-care treatment for unresectable hepatocellular carcinoma (uHCC), vs licensed/license in-progress comparators. Using inverse probability of treatment weighting (IPTW) and network meta-analysis (NMA), updated evidence for lenvatinib monotherapy from LEAP-002, in addition to evidence from REFLECT, was included in the analyses.

Randomized controlled trials (RCTs) were identified via systematic review. REFLECT and LEAP-002 investigated lenvatinib in uHCC, with patient-level data available for each; however, only REFLECT included a comparator arm of interest (sorafenib). The lenvatinib arm from LEAP-002 was adjusted to match aggregate data for confounding factors from REFLECT using IPTW. Weighted Cox regressions, including matching variables as covariates, were used to derive hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS). These HR estimates were included in Bayesian NMAs to compare lenvatinib with comparators; survival was significantly improved if the 95% credible interval for the HR did not include 1.0. Scenario analyses explored alternative choices for IPTW estimators.

Eight RCTs (including REFLECT) and the single-arm adjusted lenvatinib data from LEAP-002 were included in the NMA base case. Lenvatinib demonstrated significant improvement in OS compared with sorafenib 400 mg twice daily (BID) and significant improvement in PFS compared with sorafenib 400 mg BID, tremelimumab 300 mg plus durvalumab 1500 mg every 4 weeks (Q4W), and durvalumab 1500 mg Q4W.

These results suggest that patients with uHCC treated with lenvatinib have similar or significantly improved OS and PFS compared with licensed/license in-progress therapies.

Cognitive behavior therapy (CBT) has been shown to be effective in improving depression in patients with cancer. However, diversity exists in the CBT delivery formats, and the optimal delivery format remains unconfirmed.

To compare the efficacy of different delivery formats of CBT interventions on depression in patients with cancer.

Network meta-analysis of randomized controlled trials.

Six databases, including PubMed, Web of Science, Embase, CINAHL, the Cochrane Central Register of Controlled Trials and PsycINFO, were searched from inception to May 30, 2024.

Two reviewers independently conducted study inclusion, data extraction, and risk of bias assessment. A pairwise meta-analysis and a network meta-analysis were performed sequentially to determine the efficacy of CBT delivery formats for improving depression in patients with cancer.

A total of 34 randomized controlled trials involving six delivery formats of CBT were included. Face-to-face group CBT (SMD = -0.88, 95% CI [-1.33, -0.44]), internet-based individual CBT (SMD = -0.49, 95% CI [-0.92, -0.06]), app-based individual CBT (SMD = -0.81, 95% CI [-1.45, -0.18]), and combined delivery formats of CBT for individual (SMD = -0.35, 95% CI [-0.62, -0.09]) were significantly more effective than the inactive control. The ranking probabilities revealed that face-to-face group CBT (P-score = 0.86), app-based individual CBT (P-score = 0.74) and internet-based individual CBT (P-score = 0.57) were the three most effective delivery formats of CBT.

This study revealed the efficacy ranking of different CBT delivery formats in improving depression in patients with cancer. These findings are expected to provide evidence-based support for future research and clinical decision making for improving depression in patients with cancer.

Several surgical techniques have been used to treat cervical dystonia (CD), however, to date, the optimal surgical technique for CD remains controversial. We therefore conducted the first network meta-analysis to compare different surgical strategies for CD to inform clinical practice.

Electronic databases were searched for surgical strategies for treating CD. The primary outcome was improvement in total Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) score. Subgroup analysis was performed to compare short-term (< 1 year) and long-term (≥ 1 year) outcomes. Safety outcomes included surgery-related adverse events (AEs).

A total of 55 trials with 2032 patients employing five surgical strategies were identified, including globus pallidus internus (GPi)/subthalamic nucleus (STN)-deep brain stimulation (DBS), selective peripheral denervation (SPD), microvascular decompression (MVD) and pallidotomy. All strategies led to significant improvement in total TWSTRS score (mean improvement range 18.65-28.22). GPi-DBS showed significantly greater enhancement than SPD for the whole dataset (mean difference [MD] 7.03, 95% credible interval [Crl] 1.53-12.56), while both GPi-DBS (MD 8.05, 95% Crl 2.35-13.80) and STN-DBS (MD 10.71, 95% Crl 2.22-19.20) exhibited more long-term improvement than SPD. Regarding safety outcomes, GPi/STN-DBS and MVD were associated with fewer surgery-related AEs than SPD (ln odds ratio range -1.68 to -1.41).

We conclude that DBS should be the preferred surgical option for CD, and the STN is a promising alternative target choice due to its comparable efficacy with the GPi. However, more direct evidence is still required.

Symptomatic denture stomatitis (DS) is a painful oral mucosal disorder that can impair quality of life in denture wearers. A complete cure of DS is difficult to achieve, and the most efficacious regimen to treat DS has not yet been conclusively established.

The purpose of this network meta-analysis was to assess the comparative efficacy of interventions used for the treatment of DS.

A search was conducted for trials published in Medline, Scopus, PubMed, and Cochrane Central Register of Controlled Trials from inception until February 2022 (PROSPERO Reg no: CRD42021271366). Network meta-analysis was performed on data from randomized controlled trials that assessed the comparative efficacy of any form of intervention for the treatment of DS in denture wearers. Agents were ranked according to their effectiveness in the treatment of DS based on outcomes using surface under the cumulative ranking (SUCRA).

A total of 25 articles were included in the quantitative analysis. Topical antifungal agents (risk ratio [RR]=4.37[95% confidence interval [CI]: 2.15,8.90), topical antimicrobial agents used along with systemic antifungal agents (RR=4.25[95% CI: 1.79,10.33]), systemic antifungal agents (RR=4.25[95% CI: 1.79,10.10]), photodynamic therapy (RR=4.25[95% CI: 1.75,8.98]), and topical plant products (RR=3.40[95% CI: 1.59,7.26]) were found to effectively improve DS. Microwave disinfection concurrently administered with topical antifungal agents (RR=7.38(95% CI: 2.75,19.81), microwave disinfection 7.38[95% CI: 2.75,19.81]), topical antifungal agents (RR=4.88[95% CI: 1.92,12.42]), topical plant products (RR=4.49[95% CI: 1.70,11.82]), systemic antifungal agents together with topical antimicrobial agents (RR=3.85[95% CI: 1.33,11.10]), topical antimicrobial agents (RR=3.39[95% CI: 1.17,9.81]), systemic antifungal agents (RR=3.37[95% CI: 1.21,9.34]), and photodynamic therapy or photochemotherapy (PDT) (RR=2.93[95% CI: 1.01,8.47]) were found to effectively resolve mycological DS. Topical antifungals ranked highest in the SUCRA ranking for clinical improvement, whereas microwave disinfection concurrently administered with topical antifungal agents ranked highest for mycological resolution. None of the agents demonstrated significant side effects except for topical antimicrobial agents which demonstrated altered taste and staining of oral structures.

Available evidence suggests that topical antifungals, microwave, and systemic antifungals are effective in the treatment of DS, but confidence in these findings is low because of the limited number of studies and a high risk of bias. Additional clinical trials are needed on photodynamic therapy, topical plant products, and topical antimicrobials.

This network meta-analysis (NMA) aimed to compare the clinical advantage of four commonly used peritoneal dialysis catheters (PDCs) including the Swan neck segment with straight tip (Swan neck + S), Tenckhoff segment with straight tip (Tenckhoff + S), Swan neck segment with coiled tip (Swan neck + C) and Tenckhoff segment with coiled tip (Tenckhoff + C).

Randomised clinical trials were searched from PubMed, Embase, the Cochrane Register of clinical trials, China National Knowledge Infrastructure (CNKI) and ChinaInfo from their inception until July 31, 2022. Meta-analysis was performed using Stata 14.0 and RevMan 5.3.5 software to evaluate the four commonly used PDCs.

Seventeen studies involved 1578 participants were included. NMA showed that compared with Swan neck + C, Swan neck + S significantly reduced catheter tip migration (OR 0.47 95% CI 0.22-0.99). Tenckhoff + S was more effective in reducing catheter dysfunction (OR 0.42, 95% CI 0.23-0.79), catheter tip migration with dysfunction (OR 0.19, 95% CI 0.05-0.78) and catheter removal (OR 0.56, 95% CI 0.34-0.93) which were consistent with the pairwise meta-analysis. According to the surface under the cumulative ranking curve, Swan neck + S emerged as the best PDC in the reduction of catheter tip migration (83.3%), followed by Tenckhoff + S (79.4%). Moreover, Tenckhoff + S (86.5%, 76.3%) and Swan neck + S (72.3, 86.9%) ranked as the first and second PDC for 1 and 2-year technique survival which was significantly higher than those of the other two PDCs.

Our NMA showed Swan neck + S and Tenckhoff + S tended to be more efficacious than Swan neck + C and Tenckhoff + C in lowering the mechanical dysfunction and prolonging the technique survival, which may contribute to better clinical decisions. More randomised controlled trials with larger scales and higher quality are needed in order to obtain more credible evidence.

To evaluate the efficacy of chondroitin sulfate (CS) and glucosamine (GS), the most relevant drugs of "Symptomatic Slow Acting Drug for Osteoarthritis" (SYSADOA), in the functional and symptomatic improvement of temporomandibular dysfunction. Although, controversy exists regarding their benefit.

An electronic search was conducted to retrieve randomized controlled clinical trials (RCTs). The risk of bias assessment was evaluated using the Cochrane Collaboration's tool. Data were meta-analyzed with a random effect model whenever possible.

Three RCTs were included. Qualitative results showed a decrease in pain, joint noise, and inflammatory biomarkers in synovial fluid and an improvement in maximum mouth opening without significant adverse effects. Meta-analysis showed a significant increase in maximum mouth opening with the use of CS-GS (p = 0.19). No statistically significant differences were found in pain reduction compared to tramadol.

CS-GS is effective and safe in the symptomatic and functional improvement of patients with TMD.

To compare five pulmonary surfactant (PS) administration strategies for neonates with respiratory distress syndrome (RDS), including intubation-surfactant-extubation (InSurE), thin catheter administration, laryngeal mask airway (LMA), surfactant nebulization (SN), and usual care, with a particular emphasis on the comparison of the LMA and SN with other strategies.

We conducted a systematic search of MEDLINE, EMBASE, PUBMED, and Cochrane CENTRAL databases up to November 2023. Two authors independently conducted data extraction, and assessed bias using the Cochrane Risk of Bias Tool. Frequency-based random-effects network meta-analyses were executed.

A total of 36 trials and 4035 infants were included in the analysis. LMA (OR: 0.20, 95%CI: 0.09 to 0.42) and Less Invasive Surfactant Administration (LISA) (OR: 0.17, 95%CI: 0.09 to 0.32) significantly reduced intubation rates compared to usual care. SN had a higher intubation rate compared to LISA (OR: 3.36, 95%CI: 1.46 to 7.71) and LMA (OR: 2.92, 95%CI: 1.10 to 7.71). LMA had a higher incidence of BPD compared to LISA (OR: 2.59, 95%CI: 1.21 to 5.54). SN ranked second to LISA in preventing BPD and death, but its efficacy decreased after excluding high-risk studies. SN and LMA had the lowest incidence of adverse events during administration.SN had the highest likelihood of secondary administration. Most results were rated as low or very low quality, with findings related to SN significantly impacted by high-risk trials.

The thin catheter strategy minimized intubation risk and showed a better composite effect in reducing both mortality and BPD incidence. SN and LMA each showed safety and some clinical benefits in the subpopulations where they were studied, but their efficacy needs further validation through high-quality studies.

 This study was registered in PROSPERO (CRD42023463756).

Available therapies for peripheral nerve injury (PNI) include surgical and non-surgical treatments. Surgical treatment includes neurorrhaphy, grafting (allografts and autografts) and tissue-engineered grafting (artificial nerve guide conduits), while non-surgical treatment methods include electrical stimulation, magnetic stimulation, laser phototherapy and administration of nerve growth factors. However, the treatments currently available to best manage the different PNI manifestations remain undetermined. This systematic review and network meta-analysis (NMA) aims to address this and determine the best treatment or combination of treatments for PNI.

A comprehensive search of MEDLINE (via PubMed), Embase, Cochrane Library, Web of Science, Chinese Biomedical Database, China National Knowledge Infrastructure, VIP Database, Wanfang Database, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov and the Chinese Clinical Trial Register will be completed using the following keywords: peripheral nerve injury, therapies and related entry terms. Studies will be included based on specific eligibility criteria, and the reference lists of the included studies will be manually searched. Relevant data will be extracted from the included studies using a specially designed data extraction sheet. The risk of bias in the included studies will be assessed, and the overall strength of the evidence will be summarised. A random-effects model was used for all pairwise meta-analyses (95% CI). Bayesian NMA is used to explore the relative benefits of various treatments. The review will be reported using the Preferred Reporting Items for Systematic Reviews incorporating NMA statement.

As the protocol for this systematic review and Bayesian NMA is based on studies with published results and does not involve patient interventions, no ethical review is required. The results will be published in a peer-reviewed journal.

To evaluate the association between anti-diabetic agents and the risks of dementia in patients with type 2 diabetes (T2D).

Literature retrieval was conducted in PubMed, Embase, the Cochrane Central Register of Controlled Trials and Clinicaltrial.gov between January 1995 and October 2024. Observational studies and randomized controlled trials (RCTs) in patients with T2D, which intercompared anti-diabetic agents or compared them with placebo, and reported the incidence of dementia were included. Conventional and network meta-analyses of these studies were implemented. Results were exhibited as the odds ratio (OR) or risk ratio (RR) with 95% confidence interval (CI).

A total of 41 observational studies (3,307,483 participants) and 23 RCTs (155,443 participants) were included. In the network meta-analysis of observational studies, compared with non-users, sodium glucose cotransporter-2 inhibitor (SGLT-2i) (OR = 0.56, 95%CI, 0.45 to 0.69), glucagon-like peptide-1 receptor agonist (GLP-1RA) (OR = 0.58, 95%CI, 0.46 to 0.73), thiazolidinedione (TZD) (OR = 0.68, 95%CI, 0.57 to 0.81) and metformin (OR = 0.89, 95%CI, 0.80 to 0.99) treatments were all associated with reduced risk of dementia in patients with T2D. The surface under the cumulative ranking curve (SUCRA) evaluation conferred a rank order as SGLT-2i > GLP-1RA > TZD > dipeptidyl peptidase-4 inhibitor (DPP-4i) > metformin > α-glucosidase inhibitor (AGI) > glucokinase activator (GKA) > sulfonylureas > glinides > insulin in terms of the cognitive benefits. Meanwhile, compared with non-users, SGLT-2i (OR = 0.43, 95%CI, 0.30 to 0.62), GLP-1RA (OR = 0.54, 95%CI, 0.30 to 0.96) and DPP-4i (OR = 0.73, 95%CI, 0.57 to 0.93) were associated with a reduced risk of Alzheimer's disease while a lower risk of vascular dementia was observed in patients receiving SGLT-2i (OR = 0.42, 95%CI, 0.22 to 0.80) and TZD (OR = 0.52, 95%CI, 0.36 to 0.75) treatment. In the network meta-analysis of RCTs, the risks of dementia were comparable among anti-diabetic agents and placebo.

Compared with non-users, SGLT-2i, GLP-1RA, TZD and metformin were associated with the reduced risk of dementia in patients with T2D. SGLT-2i, and GLP-1RA may serve as the optimal choice to improve the cognitive prognosis in patients with T2D.

To optimize patient outcomes, healthcare decisions should be based on the most up-to-date high-quality evidence. Randomized controlled trials (RCTs) are vital for demonstrating the efficacy of interventions; however, information on how an intervention compares to already available treatments and/or fits into treatment algorithms is sometimes limited. Although different therapeutic classes are available for the treatment of chronic obstructive pulmonary disease (COPD), assessing the relative efficacy of these treatments is challenging. Synthesizing evidence from multiple RCTs via meta-analysis can help provide a comprehensive assessment of all available evidence and a "global summary" of findings. Pairwise meta-analysis is a well-established method that can be used if two treatments have previously been examined in head-to-head clinical trials. However, for some comparisons, no head-to-head studies are available, for example the efficacy of single-inhaler triple therapies for the treatment of COPD. In such cases, network meta-analysis (NMA) can be used, to indirectly compare treatments by assessing their effects relative to a common comparator using data from multiple studies. However, incorrect choice or application of methods can hinder interpretation of findings or lead to invalid summary estimates. As such, the use of the GRADE reporting framework is an essential step to assess the certainty of the evidence. With an increasing reliance on NMAs to inform clinical decisions, it is now particularly important that healthcare professionals understand the appropriate usage of different methods of NMA and critically appraise published evidence when informing their clinical decisions. This review provides an overview of NMA as a method for evidence synthesis within the field of COPD pharmacotherapy. We discuss key considerations when conducting an NMA and interpreting NMA outputs, and provide guidance on the most appropriate methodology for the data available and potential implications of the incorrect application of methods. We conclude with a simple illustrative example of NMA methodologies using simulated data, demonstrating that when applied correctly, the outcome of the analysis should be similar regardless of the methodology chosen.

Allergic rhinitis (AR) is a widespread inflammatory disorder of the nasal mucosa affecting millions globally. The increasing prevalence of AR underscores the need for effective treatment modalities. Acupuncture has been identified as a potential non-pharmacological intervention for AR due to its effects on autonomic nerve functions and neuroendocrine and immune networks. However, a comprehensive evaluation of different acupuncture techniques through high-quality, evidence-based research is still needed.

Randomised controlled trials of different acupuncture-related therapies for postmenopausal osteoporosis will be searched in the following databases from 1 January 2002 to 31 December 2022, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP Database, Wanfang Database and China Biomedical Literature Database. Overall, clinical efficacy rate, bone mineral density and a Visual Analogue Scale score are used as the primary outcome indicators. In addition, the secondary outcome indicator is adverse reactions. Meanwhile, Stata (V.14.0) and RevMan (V.5.4) will be used to conduct the network meta-analysis. If the data are permissible and feasible, we will also perform meta-regression and subgroup analyses to address the underlying causes of data inconsistency and heterogeneity in the statistical analyses. To improve the credibility of this network meta-analysis, we will evaluate the quality of evidence in this research according to the GRADE assessment.

The current guidelines and canonical norms of diagnosis or treatment for Post-traumatic stress disorder (PTSD) with sleep disorder are still conflicting and have not yet reached a consensus. This study aimed to unravel the most effective countermeasures between two categories (psychotherapy and pharmacotherapy) put forward by the National Institute for Health and Clinical Excellence (NICE) and World Federation of Societies of Biological Psychiatry (WFSBP) respectively to treat PTSD individuals co-exist with sleep disorders.

Four databases, including PubMed, EMBASE, Cochrane Library, and APA PsyNet, were searched from inception to February 02, 2023.

Twenty articles with 24 Randomized controlled trials (RCTs) and a total number of 1,647 participants were included. As demonstrated in the network meta-analysis comparison results, CBT-I (standardized mean differences (SMD) = -1.51,95% confidence interval (CI):-2.55 to -0.47), CBT-I plus IRT (SMD = -1.71, 95%CI:-3.39, -0.03), prazosin (SMD = -0.87,95%CI:-1.59 to -0.16) and hydroxyzine (SMD = -1.06, 95%CI: -1.94 to -0.19) significantly reduced PTSD symptoms compared with placebo. In contrast to placebo, CBT-I (SMD = -5.61,95%CI:-8.82 to -2.40) significantly improved sleep quality. For nightmare severity, IRT (SMD =-0.65, 95%CI:-1.00 to -0.31), prazosin (SMD = -1.20,95%CI:-1.72 to -0.67) and hydroxyzine (SMD = -0.98,95%CI:-1.58 to -0.37) significantly reduced nightmare severity in comparison with placebo.

This study suggested that under most circumstances, psychotherapy namely CBT-I had a favorable profile, but pharmacotherapy with prazosin was effective in managing nightmare severity. The sole avail of CBT-I was recommended to improving sleep quality while CBT-I and CBT-I plus IRT showed excellent management of PTSD symptom severity. Exposure to CBT-I isrecommended for depression. The relevant clinical guidelines for the management of individuals with PTSD and sleep disorders may regard this as a reference.

TNT is now considered the preferred option for stage II-III locally advanced rectal cancer (LARC). However, the prognostic benefit and optimal sequence of TNT remains unclear. This network meta-analysis (NMA) compared short- and long-term outcomes amongst patients with LARC receiving total neoadjuvant therapy (TNT) as induction (iTNT) or consolidation chemotherapy (cTNT) with those receiving neoadjuvant chemoradiation (nCRT) alone. A systematic literature search was performed between 2012 and 2023. A Bayesian NMA was conducted using a Markov Chain Monte Carlo method with a random-effects model and vague prior distribution to calculate odds ratios (OR) with 95% credible intervals (CrI). The surface under the cumulative ranking (SUCRA) curves were used to rank treatment(s) for each outcome. In total, 11 cohorts involving 8360 patients with LARC were included. There was no significant difference in disease-free survival (DFS) and overall survival (OS) amongst the 3 treatments. Compared with nCRT, both cTNT (OR 2.36; 95% CrI, 1.57-3.66) and iTNT (OR 1.99; 95% CrI, 1.44-2.95) significantly improved complete response (CR) rate. Notably, cTNT ranked as the best treatment for CR (SUCRA 0.90) and iTNT as the best treatment for 3-year DFS and OS (SUCRA 0.72 and 0.87, respectively). Both iTNT and cTNT strategies significantly improved CR rates compared with nCRT. cTNT was ranked highest for CR rates, while iTNT was ranked highest for 3-year survival outcomes. However, no other significant differences in DFS, OS, sphincter-saving surgery, R0 resection and postoperative complications were found amongst the treatment groups.

Network meta-analysis (NMA) combines evidence from multiple trials to compare the effectiveness of a set of interventions. In many areas of research, interventions are often complex, made up of multiple components or features. This makes it difficult to define a common set of interventions on which to perform the analysis. One approach to this problem is component network meta-analysis (CNMA) which uses a meta-regression framework to define each intervention as a subset of components whose individual effects combine additively. In this article, we are motivated by a systematic review of complex interventions to prevent obesity in children. Due to considerable heterogeneity across the trials, these interventions cannot be expressed as a subset of components but instead are coded against a framework of characteristic features. To analyse these data, we develop a bespoke CNMA-inspired model that allows us to identify the most important features of interventions. We define a meta-regression model with covariates on three levels: intervention, study, and follow-up time, as well as flexible interaction terms. By specifying different regression structures for trials with and without a control arm, we relax the assumption from previous CNMA models that a control arm is the absence of intervention components. Furthermore, we derive a correlation structure that accounts for trials with multiple intervention arms and multiple follow-up times. Although, our model was developed for the specifics of the obesity data set, it has wider applicability to any set of complex interventions that can be coded according to a set of shared features.

This study aims to conduct a systematic review and network meta-analysis to evaluate the efficacy and safety of specific corticosteroids, including but not limited to hydrocortisone, methylprednisolone, prednisolone, and dexamethasone, in the treatment of severe community-acquired pneumonia (SCAP). Efficacy will be assessed using specific outcomes, such as 30-day mortality and the requirement for mechanical ventilation. Safety evaluations will include adverse events like gastrointestinal bleeding and healthcare-associated infections. The study seeks to address the gaps identified in the latest guidelines regarding the optimal use of different corticosteroid types and to provide recommendations for clinical practice.

This study conducted a comprehensive search of Medline, Embase, and the Cochrane Central Register of Controlled Trials, covering the period from inception until 22 June 2023. Randomized clinical trials for corticosteroid use among adults with SCAP were collected.

Two researchers independently assessed study eligibility based on titles and abstracts, with any disagreements resolved through discussion or consultation with a third researcher.

Two researchers independently collected and clarified study details, with a third researcher adjudicating in case of disputes.

The data from 13 randomized clinical trials involving 2,495 patients, were analyzed using a random-effects model. Eleven trials were assessed as low risk, while two were assessed as high risk. Trials were rated as having low bias risk. Results, presented as risk ratios (RR) with a 95% confidence interval (CI), indicated that hydrocortisone outperformed prednisolone (RR 0.35; 95% CI 0.10-0.94), methylprednisolone (RR 0.41; 95% CI 0.15-0.89), and placebo (RR 0.35; 95% CI 0.16-0.59) in reducing 30-day mortality. A rankogram plot suggested that hydrocortisone had the highest probability of being the most effective treatment for this outcome within the analyzed group.

In this network meta-analysis, while hydrocortisone showed greater efficacy than prednisolone, methylprednisolone, and placebo in reducing 30-day mortality in patients with SCAP, further Randomized Controlled Trials (RCTs) are required to confirm these findings before drawing definitive conclusions.

The application of network meta-analysis is becoming increasingly widespread, and for a successful implementation, it requires that the direct comparison result and the indirect comparison result should be consistent. Because of this, a proper detection of inconsistency is often a key issue in network meta-analysis as whether the results can be reliably used as a clinical guidance. Among the existing methods for detecting inconsistency, two commonly used models are the design-by-treatment interaction model and the side-splitting models. While the original side-splitting model was initially estimated using a Bayesian approach, in this context, we employ the frequentist approach. In this paper, we review these two types of models comprehensively as well as explore their relationship by treating the data structure of network meta-analysis as missing data and parameterizing the potential complete data for each model. Through both analytical and numerical studies, we verify that the side-splitting models are specific instances of the design-by-treatment interaction model, incorporating additional assumptions or under certain data structure. Moreover, the design-by-treatment interaction model exhibits robust performance across different data structures on inconsistency detection compared to the side-splitting models. Finally, as a practical guidance for inconsistency detection, we recommend utilizing the design-by-treatment interaction model when there is a lack of information about the potential location of inconsistency. By contrast, the side-splitting models can serve as a supplementary method especially when the number of studies in each design is small, enabling a comprehensive assessment of inconsistency from both global and local perspectives.

Malpositioning of the acetabular cup during total hip arthroplasty (THA) can lead to complications. Robotic surgery and navigation techniques aim to address this issue, but there is limited evidence regarding which method can achieve better clinical outcomes. Therefore, this network meta-analysis (NMA) aimed to compare the efficacy of various navigation methods.

This NMA of prospective randomized controlled trials compared robot-assisted systems (RAS), computer-assisted navigation systems (CAS), augmented reality-based portable navigation (AR), patient-specific instrumentation (PSI), portable accelerometer-based navigation (PN), and conventional methods (C) for THA procedures. We searched MEDLINE, EMBASE, Cochrane, Central Register of Controlled Trials, International Clinical Trials Platform Search Portal, and ClinicalTrials.gov. databases. The primary outcomes included revision surgery and postoperative clinical scores, and the secondary outcomes encompassed cup placement accuracy, acetabular cup placement outliers from the Lewinnek safe zone, surgical time, and complications. We used a Bayesian random-effects NMA, and confidence of evidence was assessed using confidence in NMA.

We identified 45 studies including 2,122 patients. We did not find large differences in revision surgery, clinical outcome scores, cup inclination, or anteversion angle accuracy among the modalities. AR, CAS, and PSI exhibited a lower risk of outliers from safe zones than C. In addition, RAS and CAS had a longer surgical time than C.

Robotic and navigation tools did not reduce the revision risk or enhance clinical outcomes. AR, CAS, PSI, and PN may decrease the risk of cup placement outliers in safe zones. However, the cup placement accuracy was equivalent, and the surgical time may be longer in RAS and CAS than in C.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: Primary objective: to assess the benefits and harms of currently recommended regimens as the first-line therapy in high-risk people with chronic lymphocytic leukemia, using network meta-analysis Secondary objectives: to assess whether the benefits and harms of the recommended regimens differ according to sex, Rai stage, or genetic mutation status to estimate the ranking of treatments for overall survival, progression-free survival, objective response rate, complete response rate, minimal residual disease, and serious adverse events to estimate the overall rate of adverse events and serious adverse events.

The rise of opioid-free anaesthesia (OFA) aims to reduce postoperative pain while reducing opioid-related side effects during surgery. However, the various adjuvant agents used in OFA complicate the evaluation of their effectiveness and risks. Recent reviews question the clinical benefits of OFA, highlighting the need for thorough evaluation. This protocol describes a network meta-analysis to compare the effectiveness of OFA with opioid-based anaesthesia and will identify key components for optimal postoperative outcomes.

We will perform a systematic search of literature published in English without time restriction in Embase, The Cochrane Library, MEDLINE (via PubMed) and CINAHL, along with Google Scholar for grey literature. The final search will be performed on 1 October 2024. We will include randomised controlled trials with adult patients undergoing surgery with general anaesthesia, excluding preclinical, observational, regional anaesthesia-only and prolonged anaesthesia outside the operating room studies. The primary outcome is postsurgical pain scores, with secondary outcomes including quality of recovery, opioid consumption, adverse effects and long-term events. We will assess bias using the Cochrane risk of bias 2 tool and conduct Bayesian network meta-analyses for pooled estimates. We will report effect estimates as ORs and standardised mean differences with 95% credible intervals and assess certainty using GRADE methodology.

Ethics approval is not required for this systematic review. Results will be published in a peer-reviewed journal and presented at national and international anaesthesia and pain management conferences.

This systematic review compared the efficacy of traditional Chinese medicine (TCM) treatments for outcomes of different stages and labor pain among pregnant women.

Eight databases were electronically searched for TCM on labor pain between January 2012 and January 2022. The studies were recorded and screened according to inclusion criteria and subsequently entered in Note Express. The quality of the included studies was evaluated using the Cochrane risk of bias tool, and network meta-analysis was conducted with Stata 16.0. Forest plots and league tables were used to compare different treatment modalities' effect sizes. Additionally, the probabilities of various treatment modalities for each outcome under the cumulative ranking curve were determined. The protocol was registered in PROSPERO (CRD42022336091). This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

Thirty articles encompassing 3277 participants were included in the network meta-analysis with 9 different treatment modalities. In terms of pain of labor at 30 minutes, acupuncture + autonomic nerve block was the most effective treatment modality. With regard to the 60-minute pain and the first stage of labor, acupressure + acupuncture therapy was most effective.

In general, a combined treatment with acupressure and acupuncture is the most effective approach for relieving labor pain and shortening the duration of labor. Based on these data, we intend to explore further clinical TCM therapy for relieving maternal pain.
