Effects of bariatric surgery on obesity associated gastroesophageal reflux disease: Insights from a systematic review and network meta-analysis

Figure 1  Literature screening process.

Figure 2  Traffic light plot showing the risk of bias assessment of the included studies.

Figure 3  Risk of bias traffic light plot for the included studies.

Figure 4 Network plot of the direct comparisons among the included interventions. A: Body mass index reduction; B: Percent excess weight loss; C: Gastroesophageal reflux disease remission; D: Gastroesophageal reflux disease onset; E: Change in proton pump inhibitor usage; F: Change in esophagitis; G: Complication. The line thickness represents the number of studies comparing the connected interventions. OAGB: One-anastomosis gastric bypass; RYGB: Roux-en-Y gastric bypass; SG: Sleeve gastrectomy.

Figure 5 Surface under the cumulative ranking curve plot showing the probability of each intervention as the most effective. A: Body mass index reduction; B: Percent excess weight loss; C: Gastroesophageal reflux disease remission; D: Gastroesophageal reflux disease onset; E: Change in the proton pump inhibitor usage; F: Change in esophagitis; G: Complication. Higher surface under the cumulative ranking curve values indicates a higher likelihood of being the best treatment. OAGB: One-anastomosis gastric bypass; RYGB: Roux-en-Y gastric bypass; SG: Sleeve gastrectomy.
