Figure 1  Comparison between one-anastomosis gastric bypass and sleeve gastrectomy regarding complete diabetes remission and excess weight loss (Preferred Reporting Items for Systematic reviews and Meta-Analyses chart).

Figure 2 Complete diabetes remission following one-anastomosis gastric bypass and sleeve gastrectomy. A: At 1 year following surgery (forest plot); B: At 1 year following surgery (funnel plot); C: At 3 years following surgery; D: At 5 years following surgery. OAGB: One-anastomosis gastric bypass; CI: Confidence interval.

A: At 1 year following surgery (forest plot); B: At 1 year following surgery (funnel plot); C: At 3 years following surgery; D: At 5 years following surgery. OAGB: One-anastomosis gastric bypass; CI: Confidence interval; OR: Odds ratio.
