Data are expressed as mean (range). For comparisons, an analysis of variance (ANOVA) or a nonparametric Kruskal-Wallis test was applied. Post hoc tests were performed when appropriate, with an unpaired -test. For dichotomous values, we used Fischer’s exact test. Comparisons: CTS vs. RYGB, CTS vs. SG, and RYGB vs. SG. Abbreviations: CTS: control subjects; RYGB: Roux-en-Y gastric bypass group; SG: sleeve gastrectomy group; BMI: body mass index; LBM: lean body mass; FM: fat mass; HbA1c: glycated haemoglobin.
