*1 No data are available for percentage loss of excess weight after biliopancreatic diversion.
*2 proximaler Roux-en-Y-gastric bypass (RYGB), mini-bypass, and bypass procedures that were not further specified.
*3 High heterogeneity in definitions of diabetes remission between primary studies and systematic reviews.
Fields are left empty if no high-quality evidence on the level of a systematic review or a meta-analysis is available.
All evidence summarized here is from systematic reviews and meta-analyses with SIGN evidence level 2+/++. The evidence tables corresponding to the systematic reviews and meta-analyses cited here are presented in the guideline report. CI, confidence interval
