Data are given as mean ± SD for parametric variables or number (column percentage) for categorical variables
Morbidly obese individuals underwent a two-step bariatric surgery intervention with sleeve gastrectomy as a first-step surgery and a Roux-en-Y gastric bypass surgery 12 ± 2 months after the first-step surgery
aThe p values were determined using paired Student’s t test for continuous parametric values and χ 2 tests for categorical values
T2D, type 2 diabetes; TG, triacylglycerol
