Weight reduction independent changes from baseline after GBP and VBG/B at the 10 year follow up (multiple linear regression analyses).

a: Unadjusted difference between year 10 and baseline within each group. Minus signs denote reductions. Means (±SD) bDifference between year 10 and baseline within each group after adjustment for change in body mass index (BMI), sex, age, baseline BMI and the baseline level of the respective variables. Minus signs denote reductions. Mean values.b: Difference between year 10 and baseline after adjustment for change in body mass index (BMI), sex, age, baseline BMI and the baseline level of the respective variables. Minus signs denote reductions. Mean values.c: Difference between gastric bypass surgery (GBP) and pure restrictive bariatric surgery (VBG/B) after adjustment for BMI change, sex, age, baseline BMI and the baseline level of the respective variables. Minus signs denote larger reductions in GBP compared to VBG/B group.
