“…Abbreviations: EBMIL, excess BMI loss; EWL, excess weight loss; MD, mean difference; OAGB, one-anastomosis gastric bypass; RYGB, Roux-en-Y gastric bypass; SG, sleeve gastrectomy; TWL, total weight loss.However, EWL (percentage) was greater in patients who underwent RYGB than SG at 3 years (3 studies, 170 patients, MD: 11.93, 95% CI: 6.90 to 16.95, I 2 : 0%, p < 0.00001; Table1, Figure2F)(31,41,42) EWL (percentage) between RYGB and OAGB Four RCTs compared EWL (percentage) between RYGB and OAGB(13,47,48,50) at different time points, as reported on Supporting Information TableS9. Results at 1 month (48), 3 months (49), 9 months (50), 24 months (47), and 60 months (48) were reported cantly more important after OAGB than after RYGB (4 studies, 208 patients, MD: −10.82, 95% CI: −18.02 to −3.62, I 2 : 68%, p = 0.003;Table 1, Figure…”
