The limited impact of randomized controlled trials on the management of greater trochanteric pain syndrome as demonstrated by fragility Indices: A citation analysis. J ISAKOS 2025; 11:100846. [PMID: 40054773 DOI: 10.1016/j.jisako.2025.100846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 01/07/2025] [Accepted: 02/24/2025] [Indexed: 03/26/2025]
Abstract
IMPORTANCE Greater trochanteric pain syndrome (GTPS) is a chronic condition commonly defined as pain in the lateral hip joint that can be severely limiting to activities of daily living, sleep, and overall quality of life. It encompasses numerous disease states causing pain in the region of the greater trochanter of the femur. Noninvasive management approaches for GTPS include corticosteroid injections and physiotherapy, preferred as first-line interventions prior to surgical interventions. Understanding the impact of randomized control trials (RCTs) can enhance the understanding of treatment paradigms. OBJECTIVE To identify factors and study characteristics associated with the impact, as measured by the citation density of RCTs in the management of GTPS. EVIDENCE REVIEW MEDLINE, EMBASE, CENTRAL, SCOPUS, and Web of Science were searched from database inception to September 5, 2023 for RCTs evaluating conservative and surgical interventions for GTPS. The inclusion criteria for this systematic review were level I evidence, assessment of at least two different approaches to the management of GTPS, published in English, and featuring human subjects. Pertinent study characteristics were extracted from the included trials after title/abstract and full-text screening. Citation metrics were obtained from the Clarivate Web of Knowledge database on September 28, 2023. The fragility index (FI) and continuous fragility index (CFI) were calculated for primary outcomes across all included RCTs. Univariate regression models were used to assess correlations between citation density and a variety of study characteristics. A sub-analysis by category of intervention (injectable modalities, non-invasive modalities, and surgical modalities) was also performed, with an ANOVA of study and bibliometric characteristics. FINDINGS Twenty-one studies published from 2009 to 2023 comprising 1683 patients (1690 hips) met inclusion criteria and were eligible for analysis. Treatments ranged from non-invasive (n = 8), injectable (n = 12), to surgical modalities (n = 1). Eleven different countries were represented amongst the included RCTs; 71.4 % were from the United States or Europe, with the remaining 28.6 % originating from Australia. The median journal impact factor of published studies was 3.4 (IQR 2.4-4.8). The mean citation density across all three intervention categories were injectable modalities (4.37 ± 3.39), noninvasive modalities (3.27 ± 1.77), and surgical modalities (1, not applicable). The median CFI was 2 (IQR 0-12). Correlation analysis demonstrated a statistically significant correlation to year published (R = -0.473, p = 0.03) and study sample size (R = 0.735, p < 0.01). CONCLUSIONS AND RELEVANCE RCTs assessing the management of GTPS demonstrate a varied range of clinical uptake, as evidenced by citation density. An array of different healthcare disciplines is involved in GTPS management, signified by the diversity of journals publishing RCTs on the topic. The median CFI is low compared to other citation analyses in orthopedics, demonstrating that the collective conclusions drawn by these studies are limited by fragility. Additionally, RCTs on surgical treatments for cases refractory to nonsurgical management are notably underrepresented, highlighting the necessity for further evaluation. LEVEL OF EVIDENCE I.

Abstract
Introduction The present investigation examined the trend of publications and ranking in Orthopaedics and Sports Medicine of European countries during the years 1996 to 2022 and compared these with all the regions globally. Methods In September 2023, the SCOPUS data of publications in Orthopaedics and Sports Medicine from the SCImago Journal & Country Rank website were retrieved. All the data from Western and Eastern Europe were extracted from the overall data of the global countries and merged into Excel files, for each of the years 1996-2022 and 2022. Results Western European countries contributed significantly to the global share of publications in Orthopaedics and Sports Medicine with nearly 1/3rd of the total publications. Eastern European countries' contribution was minimal to the global publications and was almost 10 times less than the Western European countries. The total number of publications in the area of Orthopaedics and Sports Medicine from 1996 to 2022 at the European scale was led by the United Kingdom (N = 51510) and has maintained its supremacy until recently, in 2022. Amongst Western European countries, during the cumulative period of 1996-2022, the maximum contributions were made by the United Kingdom (N = 51510), and also in 2022, the United Kingdom contributed maximally (N = 3339). In the cumulative period of 1996-2022, Poland contributed maximally (N = 4049) among the Eastern European countries. In 2022, the maximum contribution from the Eastern European countries came from the Russian Federation (N = 462). Conclusion The European continent is the major contributor to Orthopaedics and Sports Medicine research and publications, with almost 1/3rd of the global share of publications. Western European countries are far ahead in their contributions than Eastern European countries.

Abstract
Purpose Medical research is a crucial indicator of a nation's reputation and development. However, there are concerns about the limited orthopedic research in Kingdom of Saudi Arabia (KSA). Therefore, this study conducted bibliometric analysis to investigate orthopedic research output from KSA. Methods PubMed database for orthopedic articles, with a minimum of one KSA-affiliated orthopedic author published from the year 2000 onwards, was searched. This excluded duplicate articles, corrections, letters, editorials, commentaries, and brief communications. The titles of the included articles, publication years, first and corresponding authors' primary affiliations and countries, countries and institutes of research, and total citations were noted. Thereafter, year-wise research contribution, top contributing and collaborating nations, top contributing affiliations, study types, levels of evidence, journal distribution, their impact factor, h-index and quartile-related information, and citation trends were analyzed. Results The search strategy yielded 1047 eligible articles. An increasing trend in research contributions in recent years was observed, with the least number of articles (8) contributed in 2005 and the most (140) in 2023. The research was conducted in KSA for most articles (83.48%). Authors from Canada collaborated in 3.44% of the articles. King Saud University was the top contributing institution (17.38% of all articles). There were 66 (6.30%) basic science studies and 873 (83.3%) clinical studies. Among non-basic science studies, 84.51% had level IV evidence. Overall, 73.83% of articles had either first/corresponding or both authorships from KSA-affiliated orthopedic authors. The eligible articles were published in 303 journals, with a mean impact factor of 3.04 (range 0.4-51.1, 165 journals) and a mean h-index of 59.2 (range 1-367, 277 journals). Overall, 31.23% of articles with quartile information available were published in first-quartile journals. Conclusions The orthopedic research productivity in KSA is limited. However, there has been an increasing trend in orthopedic research in recent years. Nevertheless, the quality of clinical research, particularly the level of evidence, needs improvement. Therefore, further efforts should be made to strengthen research opportunities and encourage research participation among orthopedic and medical institutes.

Abstract
BACKGROUND The underrepresentation of scholarly works from low- and middle-income countries (LMICs) in academic literature is a documented concern, attributed partly to editorial biases. This trend, prevalent across various disciplines, has been less explored in the context of medical ethics journals. This study aimed to examine the composition of editorial board members (EBM) in high-impact medical ethics journals and to evaluate the extent of international diversity within these editorial teams. METHODS This study incorporated an analysis of 16 high-impact medical ethics journals. Information regarding the EBM of these journals was systematically gathered and categorized based on the World Bank's country income classifications. An in-depth examination of the editorial board compositions was then conducted. RESULTS The study identified 669 EBM across the selected journals. A predominant 89.84% (601) of these members were from high-income countries (HICs), with upper-middle-income countries contributing 7.47% (50) and lower-middle-income countries 2.69% (18). No EBM were associated with low-income countries. A regional breakdown indicated that North America was the most represented area, accounting for 48.88% (327), followed by Europe & Central Asia (27.50%, 184), East Asia & Pacific (13.45%, 90), Latin America & Caribbean (4.63%, 31), Sub-Saharan Africa (4.19%, 28), Middle East & North Africa (0.75%, 5), and South Asia (0.60%, 4). In total, these EBMs hailed from 46 different countries, with the United States representing the largest proportion (43.80%, 293), followed by the United Kingdom (13.15%, 88), Australia (7.92%, 53), Germany (6.73%, 45), and Canada (5.08%, 34). CONCLUSIONS There is a significant lack of international representation within the EBM of high-impact medical ethics journals. The majority of editors in this field are affiliated with HICs, leading to a severe underrepresentation of LMICs within the editorial boards.

Abstract
BACKGROUND The United States has witnessed significant advancements in the field of organ transplantation over the course of the last five decades, as demonstrated by a notable increase in the quantity of academic research. The presence of a highly dynamic research environment necessitates continuous evaluations to maintain the integrity and progress of the field. AIM To evaluate the total output and thematic emphasis of transplant research conducted in the United States. METHODS On January 10, 2023, we conducted a bibliometric search of United States research output in transplantation journals from the Web of Science database's Science Citation Index Expanded. We excluded editorials, meeting abstracts, and other non-article types. We analyzed annual trends, authors, institutions, articles, keywords, and countries collaborating with the United States, using VOSviewer 1.6.18 to create figures and tables. RESULTS The United States published 25956 papers (3078 reviews and 22878 articles) representing 37.7% of the world's scientific output. Canada emerged as the top collaborator with the United States, co-authoring 1263 articles. Leading institutions in United States transplantation research were the University of Pittsburgh (1749 articles), Mayo Clinic (1605 articles), Harvard Medical School (1549 articles), and Johns Hopkins University (1280 articles). The top three keywords with over 2000 occurrences were "recipients," "survival," and "outcomes," indicating a focus on graft and recipient outcome markers by United States researchers. CONCLUSION Our findings demonstrate the United States leadership in organ transplantation research, contributing significantly to the global scientific output in this field. However, opportunities exist for fostering expansive partnerships, particularly with developing countries. This study provides valuable insights into the transplantation research landscape in the United States, emphasizing the importance of ongoing evaluations to maintain and propel advancements in this critical medical discipline. The results may facilitate future collaborations, knowledge exchange, and the pursuit of innovative solutions in the realm of organ transplantation.

Abstract
PURPOSE To identify and assess the clinical impact of randomised controlled trials (RCTs) assessing the surgical management of femoroacetabular impingement syndrome (FAIS) through a citation analysis. METHODS MEDLINE, EMBASE and CENTRAL were searched from inception to April 22, 2023 for RCTs assessing the surgical management of FAIS. Study characteristics were directly abstracted from included trials and citation metrics were obtained from the Clarivate Web of Knowledge database on May 19, 2023. The continuous fragility index (CFI) was calculated for eligible outcomes. Univariate regression models were used to explore correlations between total citations per year and various study characteristics. RESULTS Ten studies comprising one thousand two hundred ninetypatients were eligible for analysis. Studies were published from 2013 to 2023. Eight countries were represented across various trials with 91% being either North American or European. The mean journal impact factor of published studies was 39.684 (median 2.982; range 1.31-202.73). The mean citation density was 14.17 (range 0.33-48.67). The median CFI was 4.8 (range 1-32.2). Correlation analysis demonstrated strong and statistically significant correlations to study sample size (R = 0.75, p = 0.012), journal impact factor (R = 0.80, p = 0.006) and continuous fragility index (R = 0.95, p = 0.015). CONCLUSION Trials assessing the surgical management of FAIS present with a wide range of clinical uptake based on citation density and are published in journals of broadly variable impact factor. Despite promising citation metrics, high-quality evidence on arthroscopy for FAIS is limited to the United States and Europe with an unclear international impact. Future knowledge translation efforts are warranted to maximise the international uptake of evidence regarding arthroscopic management of FAIS. LEVEL OF EVIDENCE I.

Abstract
BACKGROUND Although low- and middle-income countries (LMIC) have great disease burden, but the lack of studies from LMIC have been shown in several fields. Multiple researchers from LMIC perceive editorial bias against their studies. Editorial board members (EBMs) from LMIC are under-represented across many medical journals. It is still unclear whether this phenomenon exists in the field of hand research. The purpose of this study was to investigate the composition of EBMs in leading subspecialty hand journals, and to reveal the international representation of EBMs in the field of hand research. METHODS This cross-sectional study included seven leading subspecialty hand journals. The EBMs were obtained from the journals' websites. The country affiliations of EBMs were categorized based on their locations and economy status. The composition of EBMs was investigated. RESULTS There were 211 EBMs in the seven journals. A total of 185 EBMs (87.7%) were affiliated with high-income countries (HIC), 18 (8.5%) with upper middle-income countries, and 8 (3.8%) with lower middle-income countries. None EBMs were affiliated with low income countries. The EBMs were affiliated with 30 countries. The biggest number of EBMs were affiliated with the USA 74 (35.07%), followed by the United Kingdom (45, 21.33%), and France (13, 6.16%). Most of EBMs were based in Europe and Central Asia (86, 40.8%) and North America (81, 38.4%). CONCLUSIONS The EBMs of leading subspecialty hand journals are dominated by HIC with a very low representation of LMIC. There is a need to make the editorial boards more international in the field of hand research.

Stem Cell Res 2023; 67:103044. [PMID: 36796251 DOI: 10.1016/j.scr.2023.103044] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 02/03/2023] [Accepted: 02/08/2023] [Indexed: 02/15/2023] Open
Abstract
Stem cell therapy has been increasingly investigated as a promising strategy for intervertebral disc degeneration (IDD). However, no international analysis of stem cell research has yet been conducted. This study aimed to analyze the major characteristics of published reports of stem cell use for IDD and to present a global insight into stem cell research. The study period spanned from the inception of the Web of Science database to 2021. A search strategy using specific keywords was implemented to retrieve relevant publications. The numbers of documents, citations, countries, journals, article types, and stem cell types were evaluated. A total of 1170 papers were retrieved. The analysis showed a significant increase in the number of papers over time (p < 0.001). High-income economies accounted for the majority of papers (758, 64.79 %). China produced the most articles (378, 32.31 %), followed by the United States (259, 22.14 %), Switzerland (69, 5.90 %), United Kingdom (54, 4.62 %), and Japan (47, 4.02 %). The United States ranked first in terms of the number of citations (10,346), followed by China (9177) and Japan (3522). Japan ranked first in terms of the number of citations per paper (74.94), followed by United Kingdom (58.54) and Canada (53.74). When standardized by population, Switzerland ranked first, followed by Ireland and Sweden. When gross domestic product was considered, Switzerland ranked first, followed by Portugal and Ireland. The number of papers was positively correlated with gross domestic product (p < 0.001, r = 0.673); however, there was no significant correlation with population (p = 0.062, r = 0.294). Mesenchymal stem cells were the most investigated stem cells, followed by nucleus pulposus-derived stem cells and adipose-derived stem cells. A sharp increase in stem cell research was observed in the field of IDD. China produced the most, although several European countries were more productive relative to their populations and economies.

Abstract
Purpose To carry out a bibliometric analysis of the scientific articles that address the topic of arthroscopy of the anterior cruciate ligament (ACL). Methods A bibliographic search of the original articles published in orthopedics journals indexed in the Web of Science database until 2020 was carried out. Evaluation of compliance with the inclusion criteria was carried out in the Rayyan web application. The Bibliometrix package in the R programming language and VOSviewer were used to perform the bibliometric analysis. Results 2249 articles published in 87 journals were included. The first publication on the subject was in 1980, and the highest number of publications was registered in 2020 (151) (annual percentage growth rate of 5.7). Fu FH was the author with the highest number of published articles, and the institutional affiliation with the highest number of original articles was the University of Pittsburgh. The most cited article was the study by Peterson et al. (2000) and the journal with the highest number of publications was Arthroscopy: the journal of arthroscopic and related surgery. United States had the highest frequency of publications and the highest number of total citations received by country. It was found on the network that the largest number of published studies had keywords such as: injuries and follow-up, whereas, in the most recent articles, the most common terms were risk-factors and outcomes. Conclusions There is a sustained increase in scientific production on ACL arthroscopy among the world scientific community. Our results can be used for collaborative research purposes and by professionals seeking training in this topic.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19127116. [PMID: 35742364 PMCID: PMC9223140 DOI: 10.3390/ijerph19127116] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 06/08/2022] [Accepted: 06/09/2022] [Indexed: 02/04/2023]
Abstract
The coronavirus disease 2019 (COVID-19) pandemic induced a sudden surge in COVID-19 related publications. This bibliometric analysis aimed to analyze literature on physical activity and COVID-19 published in the PubMed database. The search terms ((physical activity [MeSH Terms] OR physical inactivity [MeSH Terms]) AND COVID-19 [MeSH Terms]) were applied to obtain publications from the inception of PubMed to February 2022. The analyses included the year of publication, type of publication, and origin of publication by country, region, and country income. The research areas were analyzed for research articles and systematic reviews. Of 1268 articles, 143 articles were excluded, and 1125 articles were analyzed. A total of 709 articles (63.02%) were published in 2021. A majority of publications were research articles (n = 678, 60.27%). The USA (n = 176, 15.64%), countries in the European Region (n = 496, 44.09%), and high-income countries (n = 861, 76.53%) were dominant publishing countries. Of 699 research articles and systematic reviews, surveillance and trends of physical activity were the main research area, followed by health outcomes, and correlates and determinants of physical activity. There is a wide gap in publication productivity in the field of physical activity and health during the pandemic among different countries' economic statuses.

Abstract
PURPOSE Artificial intelligence (AI) has entered the field of medicine, and ophthalmology is no exception. The objective of this study was to report on scientific production and publication trends, to identify journals, countries, international collaborations, and major MeSH terms involved in AI in ophthalmology research. METHODS Scientometric methods were used to evaluate global scientific production and development trends in AI in ophthalmology using PubMed and the Web of Science Core Collection. RESULTS A total of 1356 articles were retrieved over the period 1966-2019. The yearly growth of AI in ophthalmology publications has been 18.89% over the last ten years, indicating that AI in ophthalmology is a very attractive topic in science. Analysis of the most productive journals showed that most were specialized in computer and medical systems. No journal was found to specialize in AI in ophthalmology. The USA, China, and the UK were the three most productive countries. The study of international collaboration showed that, besides the USA, researchers tended to collaborate with peers from neighboring countries. Among the twenty most frequent MeSH terms retrieved, there were only four related to clinical topics, revealing the retina and glaucoma as the most frequently encountered subjects of interest in AI in ophthalmology. Analysis of the top ten Journal Citation Reports categories of journals and MeSH terms for articles confirmed that AI in ophthalmology research is mainly focused on engineering and computing and is mainly technical research related to computer methods. CONCLUSIONS This study provides a broad view of the current status and trends in AI in ophthalmology research and shows that AI in ophthalmology research is an attractive topic focusing on retinal diseases and glaucoma. This study may be useful for researchers in AI in ophthalmology such as clinicians, but also for scientists to better understand this research topic, know the main actors in this field (including journals and countries), and have a general overview of this research theme.

Abstract
OBJECTIVES Assessment of scientific productivity provides a macroscopic view of research activity in a specific field. However, no analyses of rheumatoid arthritis (RA) have been published to date. Thus, this study aimed to investigate the characteristics of studies published on RA worldwide. METHODS The Web of Science database was searched for articles on RA published between 2017 and 2019. Analysis parameters included the number of articles, number of times each publication was cited, country, journal, and research output adjusted by population and gross domestic product. RESULTS Overall, 16,936 publications were identified. The United States was the largest contributor (17.71%), followed by China (17.17%), Japan (6.37%), the United Kingdom (5.82%), and Italy (4.76%). High-income economies (69.98%) ranked first in productivity, followed by middle- (30%) and low-income economies (0.02%). Significant correlations were found between research productivity and population (r = 0.461, p = 0.000), as well as gross domestic product (r = 0.786, p = 0.000). Publications from the United States received the highest number of total citations (21,669), followed by China (10,952) and the United Kingdom (7846). Austria had the highest average citations (16.18), followed by Norway (8.19) and the United Kingdom (7.98). When normalized by population, the leading country was Denmark, followed by the Netherlands and Sweden. When adjusted by gross domestic product, Denmark ranked first in publications on RA, followed by the Netherlands and Greece. CONCLUSION The United States emerged as the largest contributor to the field of RA research. Countries with large populations and economies tended to have higher research productivity. Multiple countries in Europe performed better in research output when normalized by population and economy sizes.

Abstract
BACKGROUND Scientific output in Southeast Asia (SEA) on the topic of dementia is postulated to be low in quality and quantity. It is also speculated that certain socioeconomic variables and measures of disease burden for dementia may play a significant role in driving the research output of a particular country. OBJECTIVE This study aimed to determine the research impact of published journal articles on dementia in SEA and its association with country-level socioeconomic factors and measures of disease burden for dementia. METHODS A systematic search was conducted using electronic healthcare databases. We included articles published on dementia until August 2019 with at least 1 author affiliated with any SEA institution. We obtained bibliometric indices, relevant socioeconomic factors, and measures of disease burden for dementia from published sources. RESULTS One thousand six articles fulfilled the inclusion criteria. The majority of publications were related to Alzheimer's disease (n = 775, 77.0%). Singapore contributed the highest number of publications (n = 457, 45.4%). Gross domestic product (GDP) per capita, % GDP for research and development, and total neurologists significantly correlated with several bibliometric indices. On the other hand, the measures of disease burden for dementia in SEA countries were not significantly associated with research productivity. CONCLUSION Research productivity in SEA on dementia has substantially increased in recent years. Augmenting GDP per capita and expanding the apportionment of resources to research and development (R&D) may have a significant role in the advancement of dementia research in SEA.

Abstract
BACKGROUND The number of scientific publications on movement disorders from Southeast Asia (SEA) is thought to be low. Thus, we looked at the movement disorders research productivity among SEA countries and its associations with country-specific socioeconomic factors. METHODS We performed a systematic search for publications indexed in PubMed, Scopus, Embase and Cochrane Central Register of Controlled Trials from January 2000 to December 2019 with at least one author from SEA. Bibliometric indices were used to evaluate research impact. The country-specific socioeconomic characteristics were also obtained. RESULTS Of the 9488 identified articles, 1567 met the eligibility criteria. There was an increasing trend in the total number of publications on movement disorders during the last two decades. Singapore had the highest contribution in all aspects, which highlights the impact of knowledge-based economy type in research productivity. Parkinsonism remained the most studied condition, followed by dystonia, chorea, and tremor. Among the socioeconomic factors, only % gross domestic product (GDP) for research and development showed a positive correlation on the number of publications of a country. On the other hand, GDP per capita, population size and the number of neurologist size did not affect research productivity. CONCLUSIONS An increasing trend in the movement disorders research output over the last 20 years was seen. Singapore had the highest contribution in all aspects which highlights the impact of economy in research productivity. Among the socioeconomic factors, only % GDP for R&D showed a positive impact on the number of publications of a country.

Abstract
Bibliometric analysis is widely utilized to evaluate global research productivity in different research topics. However, to date, there has been no assessment of worldwide research productivity associated with Sjögren's syndrome. Therefore, the aim of this study was to evaluate the global research productivity in the field of Sjögren's syndrome using bibliometric analysis. The Web of Science database was scanned with the search terms 'Sjögren's syndrome' and 'Sjögren syndrome' for publications in the period 2010-2019. Original articles and reviews were selected for analysis. The most active countries were determined, and the number of articles, citations, research productivity adjusted by population and gross domestic product were analyzed. A total of 3856 articles were identified from 65 different countries. A statistically significant trend was observed in the direction of increase (in terms of the number of articles; from 282 to 461) in the 10-year period. A total of 3004 (77.90%) articles were from high-income countries. The five most productive countries were the United States (n = 714, 18.51%), China (n = 428, 11.09%), Japan (n = 308, 7.98%), Italy (n = 299, 7.75%) and France (n = 249, 6.45%). When the number of articles was adjusted according to population, Norway was the most productive country, followed by Greece and the Netherlands. In analysis according to gross domestic product, Greece was the leading country, followed by Norway and the Netherlands. The results of this study demonstrated a remarkable growth in global research productivity on Sjögren's syndrome between 2010 and 2019. More than three quarters of the articles were from high-income countries. When population and gross domestic product were considered, relatively small European countries came to the fore.

Abstract
Background: The COVID 19 pandemic increased publication productivity enormously with numerous new COVID-19-related articles appearing daily, despite the fact that many health care workers in the partially overburdened national health care systems were faced with major challenges. Methods: In a cross-sectional, observational, retrospective study we compared and correlated 17 epidemiologic, health care system-related and health-economic factors from medical databases and intergovernmental organisations potentially influencing the COVID-19 and non-COVID-19 publication productivity between 1 January and 30 April 2020 amongst the 30 countries most severely affected by the pandemic. These factors were additionally correlated with the national pre-COVID-19 publication rate for the same pre-year period to identify potential changes in the general publication behaviour. Findings: COVID-19 and non-COVID-19 publication rates correlated strongest with access to and quality of health care (ρ = 0.80 and 0.87, p < 0.0001), COVID-19 cases per capita (ρ = 0.78 and 0.72, p < 0.0001), GDP per capita (ρ = 0.69 and 0.76, p < 0.0001), health spending per capita (ρ = 0.61 and 0.73, p < 0.0001) and the pre-COVID-19 Hirsch-Index (ρ = 0.61 and 0.62, p = 0.002 and <0.0001). Ratios of publication rates for “Cancer”, “Diabetes” and “Stroke” in 2020 versus the pre-year period were 0.88 ± 0.06, 1.02 ± 0.18 and 0.9 ± 0.20, resulting in a pooled ratio of 0.93 ± 0.06 for non-COVID-19 publications. Interpretation: There are marked geographic and national differences in publication productivity during the COVID-19 pandemic. Both COVID-19- and non-COVID-19 publication productivity correlates with epidemiologic, health care system-related and healtheconomic factors, and pre-COVID publication expertise. Countries with a stable scientific infrastructure appear to maintain non-COVID-19 publication productivity nearly at the pre-year level and at the same time use their resilience to produce COVID-19 publications at high rates.

Abstract
Bibliometric studies are important to understand changes and improvement opportunities in academia. This study compared bibliometric trends for two major sports medicine/arthroscopy journals, the American Journal of Sports Medicine® (AJSM®) and Arthroscopy® over the past 30 years. Trends over time and comparisons between both journals were noted for common bibliometric variables (number of authors, references, pages, citations, and corresponding author position) as well as author gender and continental origin. Appropriate statistical analyses were performed. A p < 0.001 was considered statistically significant. One representative year per decade was used. There were 814 manuscripts from AJSM® and 650 from Arthroscopy®. For AJSM® the number of manuscripts steadily increased from 86 in 1986 to 350 in 2016; for Arthroscopy® the number of manuscripts increased from 73 in 1985/1986, to 267 in 2006, but then dropped to 229 in 2016. There were significant increases in all bibliometric variables, except for the number of citations which decreased in Arthroscopy®. There were significant differences in manuscript region of origin by journal (p = 0.000002). Arthroscopy® had a greater percentage of manuscripts from Asia than AJSM® (19.3% vs 11.5%) while AJSM® had a greater percentage from North America (70.3% vs 59.2%); both journals had similar percentages from Europe (18.2% for AJSM® and 21.6% for Arthroscopy®). For AJSM® the average percentage of female first authors was 13.3%, increasing from 4.7% in 1986 to 19.3% in 2016; the average percentage of female corresponding authors was 7.3%. For Arthroscopy®, the average percentage of female first authors was 8.1%, increasing from 2.8% in 1985/1986 to 15.7% in 2016 (p = 0.00007). In conclusion, AJSM® and Arthroscopy® showed an increase in most variables analyzed. Although Arthroscopy® is climbing at a higher rate than AJSM® for female authors, AJSM® has an overall greater percentage of female authors.

PURPOSE To investigate the quantity and quality of articles in the field of full-endoscopic spine surgery (FESS) from different countries and assess characteristics of worldwide research productivity. METHODS Articles published from 1997 to July 23, 2018, were screened using the Web of Science database. All studies were assessed for the following parameters: the number of total publications, h-index, contribution of countries, authors, journals, and institutions. RESULTS A total of 408 articles were identified between 1997 and 2018. Between 1997 and 2017, the number of published articles tended to increase by 41 times. The largest number of articles was from China (30.15%), followed by South Korea (28.68%), the USA (13.97%), Germany (9.31%), and Japan (4.90%). The highest h-index was found for articles from South Korea (23), followed by the USA (18), Germany (16), China (11), and Japan (7). The highest number of articles was published in World Neurosurgery (12.50%), followed by Pain Physician (10.29%), Spine (6.62%), European Spine Journal (4.66%), and Journal of Neurosurgery: Spine (4.17%). Wooridul Spine Hospital published the largest number of articles (10.29%), followed by Tongji University (5.88%), University of Witten/Herdecke (5.39%), Brown University (5.15%), and Third Military Medical University (3.43%). CONCLUSIONS The number of articles published in the field of FESS has increased rapidly in the past 20 years. In terms of quantity, China is the most contributive country based on the number of publications. High-quality papers as measured by h-index and the large quantity is from South Korea (second only to China). These slides can be retrieved under Electronic Supplementary Material.

Scientific impact of multiple sclerosis and neuromyelitis optica spectrum disorder research from Southeast Asia: A bibliometric analysis. Mult Scler Relat Disord 2019; 38:101862. [PMID: 31778926 DOI: 10.1016/j.msard.2019.101862] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Revised: 11/11/2019] [Accepted: 11/17/2019] [Indexed: 02/04/2023]
Abstract
BACKGROUND Scientific productivity in the Southeast Asian (SEA) region in the field of multiple sclerosis and neuromyelitis optica spectrum disorder (MS/ NMOSD) was hypothesized to be low in magnitude. The aim of this study was to determine and compare MS/ NMOSD research outputs among the SEA countries in terms of established bibliometric indices. The association between these productivity indices and relevant country-specific socioeconomic factors was also determined. METHODS A systematic review was conducted to include all relevant published MS/ NMOSD studies in the SEA indexed in MEDLINE, Embase, Scopus and CENTRAL from the inception of these databases to August 1, 2019. Quantity of research productivity was measured in terms of the total published documents. Quality of research impact was evaluated by assessing the study designs of the published reports, publications in journals with impact factor (IF) and PlumX Metrics (citations, usage, captures, mentions and social medias). Population size, gross domestic product (GDP) per capita, percentage (%) of GDP allocated to research and development (R&D), and the total number of neurologists reported in each country were obtained from reliable published data. RESULTS Out of 3,547 articles identified, only 142 articles fulfilled the eligibility criteria; therefore, the total number of publications in the SEA region related to MS/ NMOSD was deemed low in quantity. Most studies were cross-sectional and case reports/ series; hence, most studies offered low level of evidence. Since the aggregate scores in citations, usage, captures, mentions, and social medias in PlumX Metrics and publications in journals with IF were low, the overall quality of the published articles was considered low. Thailand (57 articles), Malaysia (40) and Singapore (29) contributed to the majority of publications on the topic-. GDP per capita was statistically correlated with usage. Percent GDP for R&D was positively correlated with total publications, usage, captures and social mediaindices. CONCLUSION In conclusion, the scientific impact of MS/ NMOSD in the SEA was considered low in quantity and quality. This study must encourage researchers in the SEA to produce greater volumes of high-quality publications in this particular field and motivate governments to increase % GDP for R&D for the benefit of patients suffering fromthese rare and disabling conditions.

Abstract
Background Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. This study aims to update Korea's worldwide research productivity in the field of orthopedics using bibliometric methods and to provide Korean surgeons and researchers with insights into such research. Methods Articles published in the top 15 orthopedic journals between 2008 and 2017 were retrieved using the Web of Science. The number of articles, citations and h-index (Hirsch index), funding sources, institutions, and journal patterns were analyzed. Results Of the total 39,494 articles, Korea's contribution accounted for 5.6% (2,161 articles), ranking fifth in the world in the number of publications. Korea ranked sixth (with 29,456) for total citations worldwide but ranked 17th (13.64) in terms of average citation per item and 14th (55) in terms of h-index. Korea showed the most prolific productivity in the field of sports medicine and arthroscopy. The institution that produced the highest number of publications was Seoul National University (n = 386, 17.9%). Conclusions Orthopedic research in South Korea demonstrated high productivity in terms of the number of publications in high-quality journals between 2008 and 2017. However, total citations and average citations per article were still relatively low. Efforts should be made to increase citation rates for further improvement in research productivity in the field of orthopedics.

Abstract
PURPOSE The infection is an essential problem in the clinical practice in orthopedics. The bibliometric analysis was conducted to evaluate the top 100 cited articles on infection in orthopaedics. METHODS The Web of Science (WoS) Core Database was comprehensively searched from 1975 to 2017, and the literature search was limited in Science Citation Index Expanded (SCI-E). The subject terms included "infection", "infectious", and "infect*". All retrieved articles were filtrated by selecting the subspecialty of "Orthopedics". The searching results were listed by citation times to identify the top 100 cited articles. Significant information was elicited, including the authors, journals, countries, institutions, published year, and types of publication. RESULTS A significant increase was observed in the number of annual publications focusing on infection in orthopedics worldwide. Each of the top 100 cited articles was cited more than 150 times. Total citation times was positively associated with citation times in 2016 (P <.01) and mean citation times per year (P <.01). Conversely, age of the article was negatively associated with citation times in 2016 (P <.01) and mean citation times per year (P <.01). Besides, citation times in 2016 was positively related to mean citation times per year (P <.01). The United States was the most productive country, surgery was the most popular subspecialty and Journal of Bone and Joint Surgery American Volume was the most popular journal. CONCLUSION Infection in orthopaedics has attracted more and more researchers' concern. As for the top 100 cited articles, there were significant relationships among total citation times, citation times in 2016 and mean citation times per year as well as age of the article. The United States was the most productive country, surgery was the most popular subspecialty and Journal of Bone and Joint Surgery American Volume was the most popular journal.

Abstract
Purpose Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. However, to the best of our knowledge, no studies have documented the main characteristics of arthroplasty publications from different countries. This study aimed to evaluate the worldwide research productivity and status of Turkey in the field of arthroplasty using bibliometric methods and to provide an insight into the arthroplasty research for surgeons and researchers. Methods The Web of Science database was searched to identify arthroplasty articles published between 2006 and 2016. The contributions of countries were evaluated based on publication count, citation average, h-index and publication rate in the top 10 ranked journals. Each countries publication output was adjusted according to population size. Results A total of 26.167 articles were identified. World arthroplasty publications were increased significantly over time (p < .005). The United States was the most productive country with 9007 articles (34,4% of total) followed by England with 2939 articles (11,4 of total) and Germany with 1881 articles (7,1% of total). According to average citations per item, Scotland was in the first place followed by Denmark and Sweden, whereas in the first place according to publication output adjusted by population size was Switzerland followed by Denmark and Scotland. The United States was also in the first place according to h-index and publication rate in the top 10 ranked journals. Founding average was 28,8% (7539 of 26164) for the arthroplasty articles that were analyzed in the study. Conclusion There is a rapid increase in the number of articles in arthroplasty research from 2006 to 2016. The United States was the most productive country as measured by total publications in the arthroplasty field. However, some small European countries with high in-come have higher quality of articles and better productivity when adjusted for population. Gross domestic product (GDP) per capita and research foundation had positive affect on arthroplasty publications, both qualitatively and quantitatively.

Abstract
Background Biosimilars could be a promising option to help decrease healthcare costs and expand access to treatment. There is no previous evidence of a global bibliometric analysis on biosimilars. Therefore, we aimed to assess the quantity and quality of worldwide biosimilars research. Methods We performed a bibliometric analysis using documents about biosimilars published until December 2016 in journals indexed in Scopus. We extracted the annual research, languages, countries, journals, authors, institutions, citation frequency, and the metrics of journals. The data were quantitatively and qualitatively analyzed using Microsoft Excel 2013. Additional information about authors' participation was obtained using the R-package Bibliometrix. Publication activity was adjusted for the countries by population size. Also, author co-citation analysis and a term co-occurrence analysis with the terms included in the title and abstract of publications was presented as network visualization maps using VOSviewer. Results A total of 2330 biosimilar-related documents identified in the Scopus database, most of them were articles (1452; 62.32%). The number of documents published had an exponential increased between 2004 and 2016 (p < 0.001). The United States was the country with the highest production with 685 (29.40%) documents followed by Germany and UK with 293 (12.58%) and 248 (10.64%), respectively. Switzerland (11.05), Netherlands (5.85) and UK (3.83) showed the highest per capita ratio. The highest citation/article ratio were for the Netherlands (28.06), Spain (24.23), and France (20.11). Gabi Journal published 73 (3.13%) documents; both Biopharm International and Pharmaceutical Technology and Mabs, 41 (1.76%). Three out of top ten journals were Trade publications. Amgen Incorporated from the USA was the most prolific institution with 51 documents followed by Pfizer Inc. with 48. Terms about specific diseases and drugs were found in recent years, compared with terms such as legislation, structure, protein, dose and generic in the early years. Conclusions Research production and publication of documents on biosimilars are increasing. The majority of publications came from high-income countries. The trends in terminology use are according to state of the art in the topic, and reflects the interest in the utilization of biosimilars in diseases who are expected to obtain benefits of its use.

Abstract
UNLABELLED MINI: The time trend for the number of minimally invasive spine surgery articles showed a significant increase over time with an average of 93.23 articles per year. Among all related journals, Spine published the largest number of articles in minimally invasive spine surgery research and was the most popular one in the top five countries. STUDY DESIGN Bibliometric analysis. OBJECTIVE This study aimed to reveal the characteristics of world productivity in the field of minimally invasive spine surgery (MISS) research and to provide a general picture for surgeons and researchers. SUMMARY OF BACKGROUND DATA Significant growth has been observed in the field of MISS research in recent years. However, bibliometric studies concerning the quantity and quality of articles published in MISS journals are scarce. METHODS All the data concerning MISS in this study originate from the Web of Science (Thomson Reuters, New York, NY) without restrictions. All selected literates were evaluated in the following aspects: publication year, publication journals, author, times cited, Web of Science category, countries/territories. RESULTS A total number of 2051 articles were published worldwide. The articles published during 2000 to 2015 are more than 11.28 times when compared to those published before 2000. The United States published the largest number of articles (855/2051, 41.7%), followed by Germany (245/2051, 11.9%), South Korea (160/2051, 7.8%), China (147/2051, 7.2%), and Japan (108/2051, 5.2%) and had the highest total citations (16,626). Additionally, the United States had the highest average citations per article (12.14), followed by Japan (11.98), Germany (11.19), South Korea (11.04), and China (10.95). High-income countries published 98.73% of articles, upper-middle-income countries published 0.24% of articles, and middle-income countries published 1.03% of articles. CONCLUSION The time trend for the number of MISS articles showed a significant increase over time with an average of 93.23 articles per year.

World J Orthop 2017; 8:514-523. [PMID: 28660144 PMCID: PMC5478495 DOI: 10.5312/wjo.v8.i6.514] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 12/12/2016] [Accepted: 03/24/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To perform a bibliometric analysis of publications rates in orthopedics in the top 15 orthopaedic journals.
METHODS Based on their 2015 impact factor, the fifteen highest ranked orthopaedic journals between January 2010 and December 2014 were used to establish the total number of publications; cumulative impact factor points (IF) per country were determined, and normalized to population size, GDP, and GDP/capita, comparison to the median country output and the global leader.
RESULTS Twenty-three thousand and twenty-one orthopaedic articles were published, with 66 countries publishing. The United States had 8149 publications, followed by the United Kingdom (1644) and Japan (1467). The highest IF was achieved by the United States (24744), United Kingdom (4776), and Japan (4053). Normalized by population size Switzerland lead. Normalized by GDP, Croatia was the top achiever. Adjusting GDP/capita, for publications and IF, China, India, and the United States were the leaders. Adjusting for population size and GDP, 28 countries achieved numbers of publications to be considered at least equivalent with the median academic output. Adjusting GDP/capita only China and India reached the number of publications to be considered equivalent to the current global leader, the United States.
CONCLUSION Five countries were responsible for 60% of the orthopaedic research output over this 5-year period. After correcting for GDP/capita, only 28 of 66 countries achieved a publication rate equivalent to the median country. The United States, United Kingdom, South Korea, Japan, and Germany were the top five countries for both publication totals and cumulative impact factor points.

Abstract
Worldwide research contributions have allowed the field of fracture surgery to progress. However, to the best of our knowledge, no studies have documented the main characteristics of publications from different countries. The present study aimed to determine the quantity and quality of worldwide research in fracture surgery. The Web of Science database was searched to identify fracture articles published between 2005 and 2014. The contributions of countries were evaluated based on paper and citation numbers, and the research output of each country was adjusted according to population size. A total of 19,423 papers on the topic of fracture surgery were identified worldwide, and the total number of publications from 2005 to 2014 had significantly increased by 1.82-fold (P<0.001). The majority of papers (86.64%) were published by high-income countries (gross national income per capita ≥$12,736), 13.25% by middle-income countries ($1,046-12,735) and 0.11% by low-income countries (≤$1,045). The United States contributed the highest number of publications (33.34%), followed by the United Kingdom (9.03%), Germany (8.42%), China (5.58%) and Japan (4.18%). Furthermore, the United States ranked first according to total citations (72,640). Articles from Sweden achieved the highest average citations per paper (15.63), followed by Australia (12.84) and Canada (12.44). When the number of publications were adjusted for population size, Switzerland was the first (56.39), followed by Austria (35.43) and the Netherlands (30.68). In conclusion, the number of publications in fracture surgery increased from 2005 to 2014, and the majority of fracture papers were published by high-income countries, while few papers were published by low-income countries. The United States was the most prolific country, but based on population size, a number of smaller countries in Europe may be relatively more prolific.

Abstract
Background The field of psychiatry has seen significant progress in recent years due to worldwide contributions. National productivity, however, in the field of psychiatry is still unclear. In our study, we investigated contributions of individual nations to the field of psychiatry. Methods The Web of Science was used to perform a search from 2011 to 2015 on the subject category “psychiatry”. The total number of articles, citations and the per capita numbers were obtained to analyze the contributions of different countries. Results In psychiatry journals from 2011 to 2015, 84,760 articles were published worldwide. The most productive world areas were North America, East Asia, Europe and Oceania. The percentage of articles published in high-income countries was 87.77%, middle-income countries published 12.07%, and lower-income published 0.16%. Most articles were published by the United States (32.68%); the United Kingdom was next (8.59%), which was followed by Germany (6.77%), Australia (5.87%), and Canada (4.9%). The country with the highest number of citations (243,394) was the United States. A positive correlation was found between the population/GDP and the number of publications (P < 0.01). Australia ranked the highest when normalized to population size, and the Netherlands and Norway were next. The Netherlands ranked highest, followed by Israel and Australia when adjusted for GDP. Conclusions The authorship of most of the psychiatry articles was from high-income countries and few papers came from low-income countries. The most productive country was the United States. However, when normalized to population size and GDP, some European and Oceania countries were most productive.

Abstract
Background In China, the field of orthopedics has experienced significant growth over the past 12 years. However, the recent status of research on orthopedics among individuals in mainland China, Hong Kong, and Taiwan is unknown. In this study, we investigated characteristics and trends of orthopedics publications from these three regions. Methods Between 2003 and 2014, all articles published in 63 orthopedics journals originating from mainland China, Hong Kong, and Taiwan were identified via Science Citation Index Expanded (SCIE) database. A survey was conducted to systematically analyze the published orthopedics articles from the three regions according to the numbers of articles, study design, impact factors (IFs), citations, most prolific authors, and institutions. Additionally, we evaluated global trends in orthopedics publications, and ranked top 10 countries in terms of the total number of published articles over 12 years and the number of published articles per year. Results A total number of 123,317 articles were published in the 63 orthopedics journals between 2003 and 2014. The worldwide number of annually published orthopedics articles tended to increase during the study period. The total number of orthopedics publications from the three regions, especially in mainland China, increased markedly from 2003 to 2014. The annual number of orthopedics articles from mainland China increased from 6 in 2003 to 813 in 2014, Hong Kong increased from 32 in 2003 to 71 in 2014, and Taiwan increased from 68 in 2003 to 168 in 2014. For accumulated IFs and total citations of articles, mainland China ranked the first place, followed by Taiwan and Hong Kong. However, publications from Taiwan had the highest average citations per article, and publications from Hong Kong had the highest average IFs. Among the top 10 most prolific authors and institutions, 4 authors and 4 institutions were from Taiwan, 3 authors and 4 institutions were from mainland China, and 3 authors and 2 institutions were from Hong Kong. Conclusions The quantity of articles published in international orthopedics journals from mainland China presented a remarkable upward trend during the past 12 years. Given the relative size of the populations, it should be emphasized that mainland China still has a long way to go to achieve the academic performance of Hong Kong and Taiwan.

Abstract
INTRODUCTION Robot-assisted surgery operations are being performed more frequently in the world these years. In order to have a macroscopic view of publication activities about robotic surgery, the first bibliometric analysis was conducted to investigate the publication distributions of robotic surgery. METHODS The original articles about robotic surgery were extracted from the Science Citation Index Expanded (SCI-E) on Web of Science and analyzed concerning their distributions. We also explored the potential correlations between publications of different countries and their Gross Domestic Product (GDP). RESULTS The total number of original articles retrieved from SCI-E was 3362 from 1994 to 2015. The number of original articles published in the last decade has a burgeoning increase of 572.87% compared with that published in the former decade. The leading country was USA who have published 1402 pieces of articles (41.701%), followed by Germany with 342 (10.173%). The journal published the highest number of original articles was Journal of Endourology with 237 (7.049%), followed by Surgical Endoscopy and Other Interventional Techniques (188, 5.592%). There was strong correlations between publication numbers and GDP of different countries (r(2) = 0.889, p < 0.001). In the different medical fields, urology has the highest number of articles (n = 878, 26.007%). DISCUSSIONS The macroscopic view of research activities has the potential to guide future trend in the field of robotic surgery. CONCLUSIONS There is a skyrocket trend of robotic surgery in medical research over the last two decades, and countries with high GDP tend to make more contributions to the medical field of robotic surgery.

Abstract
Background: China has witnessed remarkable progress in scientific performance in recent years. However, the quantity and quality of nursing publications from three major regions (Mainland China, Taiwan, and Hong Kong) have not been reported. This study aimed to investigate the characteristics of scientific research productivity from Mainland China, Taiwan, and Hong Kong in the field of nursing. Methods: Articles published in the 110 nursing journals originating from Mainland China, Taiwan, and Hong Kong between 2005 and 2014 were retrieved from the Web of Science. The total number of articles published, the impact factor, and the citation count were analyzed. Results: There were 2,439 publications between 2005 and 2014 from China, including 438 from Mainland China, 1,506 from Taiwan, and 495 from Hong Kong. There was a significant increase in publications for these three regions (p < 0.05), especially for Mainland China, with a 59.50-fold increase experienced. From 2011, the number of publications from Mainland China exceeded that from Hong Kong. Taiwan had the highest total journal impact factor (2,142.81), followed by Hong Kong (720.39) and Mainland China (583.94). The mean journal impact factor from Hong Kong (1.46) was higher than that from Taiwan (1.42) and Mainland China (1.33). Taiwan had the highest total citation count (8,392), followed by Hong Kong (3,785) and Mainland China (1,493). The mean citation count from Hong Kong (7.65) was higher than that from Taiwan (5.57) and Mainland China (3.41). The Journal of Clinical Nursing was the most popular journal in the three regions. Discussion: Chinese contributions to the field of nursing have significantly increased in the past ten years, particularly from Mainland China. Taiwan is the most productive region in China. Hong Kong had the highest-quality research output, according to mean journal impact factor and mean citation count.

Abstract
Objectives The objective of this study was to identify the top 50 countries in the world in clinical neurology research and to use their data to assess the impact of a number of country-specific characteristics on scientific productivity in clinical neurology. Methods The SCImago Journal & Country Rank (SCR) web site was used to identify the top 50 countries in the world based on their total documents in clinical neurology. Using their data 5 country-specific characteristics and 6 productivity indicators (total documents, total cites, h-index, citable documents, self-cites and citations per document) were correlated and examined statistically. Results The number of universities in the world top 500 and the number of clinical neurology journals enlisted in SCR correlated significantly with each of the 6 indicators. The gross domestic product (GDP) per capita and the percentage of GDP spent on research and development (R & D) correlated significantly with 3 and 4 out of the 6 indicators respectively. The population size did not correlate significantly with any of the 6 indicators. Conclusions The number of universities in the world top 500 and the number of clinical neurology journals enlisted in SCR appear to have a strong impact on scientific productivity. GDP per capita and spending on R & D appear to have a moderate impact on productivity that is influenced by the indicator used. Furthermore, population size appears to have no significant impact on productivity in clinical neurology research.
Worldwide ranking of medical specialty research is generating interest. SCR web site integrates journal and country scientific statistics. Number of universities in world top 500 and neurology journals in SCR have strong impact on scientific productivity. GDP per capita and spending on R & D have moderate impact on productivity that is indicator-dependent. Population size has no significant impact on productivity in clinical neurology research.

Abstract
OBJECTIVE Hand and wrist research has recently shown obvious progress. The quantity and quality of publications from different nations, however, have not been analyzed. In our study, we aimed to assess the characteristics of worldwide productivity in hand and wrist literature using highly cited subspecialty journals. METHODS Literature search using the Web of Science database was conducted to identify hand and wrist articles in four highly cited subspecialty journals from 2005 to 2014. The number of articles, impact factors and citations were analyzed to evaluate the contributions of different countries. Publication activity was adjusted for the countries by population size. RESULTS A total of 4268 publications were identified. The number of articles showed a significant increase of 2.10-fold between 2005 and 2014 (p = 0.0001). North America, West Europe, and East Asia were the most prolific areas. The majority of publications (92.03%) were from high-income countries, 7.97% from middle-income countries, and no publications from lower-income countries. The United States published the most articles (53.89%), followed by United Kingdom (6.51%), Japan (6.14%), Canada (3.70%), and China (3.37%). Articles originating from the United States showed the greatest number of total 5-year impact factors (5y-IF) (4059.56) and total citations (17,998). When normalized to population size, United States ranked the first (7.16), followed by Sweden (6.53), and Netherlands (5.72). However, Netherlands (1.893) had the highest mean 5y-IF, followed by Germany (1.884) and Australia (1.883). Sweden had the highest average citations per article (11.38), followed by Germany (9.63), and Australia (9.08). CONCLUSIONS The number of publications of hand and wrist research shows a significant increase during the past 10 years. The United States is the most productive country in hand and wrist literature. However, some European countries and Australia may have higher quality of articles according to mean 5y-IF and mean citations per article.

The impact of a publication in a particular medical area is reflected by the number of times the article is included as a citation. It is not known, however, which articles are cited the most in primary care journals. In our study, we aimed to identify the 100 most cited articles in primary care medicine and analyze their characteristics.We searched the Science Citation Index Expanded for articles published in 18 primary care journals using the subject category "Primary health care." We identified 100 articles in primary health care that were the most cited. We analyzed the characteristics of these articles using the title, number of citations, citation density, year of publication, journal source, decade published, country of origin, institution, author names, and type of article.The 100 articles that were cited the most were published between the years 1977 and 2009. The 1990s decade was the most productive decade. The number of citations ranged from 117 to 775. The articles were published in 9 journals and the journal with the largest number of most cited articles (n = 33) was the Journal of Family Practice. This was followed by the British Journal of General Practice (n = 17) and the journal Family Practice (n = 16). The United States was the most productive country (n = 59); the United Kingdom was next (n = 25) and this was followed by Canada (n = 5) and The Netherlands (n = 5). The most popular article type was a review article and this was followed by a qualitative study and then methodological study.Our study provides insight into the historical development of primary care studies, based on citations, and provides the foundation for further investigations.
