Data are presented as n (%) or median (interquartile range).

¹Mann-Whitney U test for continuous variables and Pearson’s χ² test or Fisher’s exact test for categorical variables were applied;

²The excess weight was calculated from the ideal weight using a BMI of 23 kg/m² as the upper limit of normal according to the World Health Organization recommended definition of obesity for Asians;

³The incidence among female patients. LSG: Laparoscopic sleeve gastrectomy; LRYGB: Laparoscopic Roux-en-Y gastric bypass; BMI: Body mass index; OSA: Obstructive sleep apnea; GERD: Gastro-esophageal reflux disease; PCOS: Polycystic ovarian syndrome.
