Data are presented as mean ± SD. Differences between the groups are derived from nonparametric Mann–Whitney U test. BMI: body mass index; TG: triglycerides; FM: fat mass; FFM: fat-free mass; OGTT: oral glucose tolerance test; HOMA-IR: homeostasis model assessment insulin resistance; HOMA-B: homeostasis model assessment β cell function; FAI: free-androgen index; SHBG: sex hormone-binding globulin; in PCOS women versus control group; # versus the baseline state.
