Odds ratio (95%CI). Re-VBG: Revision of the vertical banded gastroplasty; cSG: Conversion to sleeve gastrectomy; cRYGB: Conversion to Roux-en-Y gastric bypass; %EWL: Excess weight loss; NA: Not available. P value is corrected for operative time, time between VBG and revision, osteo-articular disease and mean %EWL after VBG. No correction possible in logistic regression analysis due to limited events and group sizes. In case of a second revisional procedure, follow-up until second was taken into account.
