  1. Data are reported as mean (95% CI), except for 24 months postoperative in the DMH-DMH group, where the numbers in parenthesis resembles minimum and maximum values (N = 2). BMI Body mass index, CI Confidence interval, NDM Patients without diabetes mellitus (DM), DMH-NDM Patients with DM in remission after Roux-en-y gastric bypass surgery (RYGB), DMH-DMH Patients with DM not in remission after RYGB. All patients also include 15 patients who belong to other subgroups than the three showed in table; p-value from One-way ANOVA compares the three patient-subgroup means; * indicates significant difference (p < 0,05) when compared to the NDM group. No significant differences were found between the two diabetes subgroups
