Data is shown as means ± SD or median and interquartile ranges.
P: PCOS group compared with non-PCOS group.
^aBMI ≥ 23 kg/m² subgroup compared with 18.5 ≤ BMI < 23 kg/m² subgroup, P < 0.05 means significantly different.
^bBMI ≥ 23 kg/m² subgroup compared with BMI < 18.5 kg/m² subgroup, P < 0.05 means significantly different.
^c18.5 ≤ BMI < 23 kg/m² subgroup compared with BMI < 18.5 kg/m² subgroup, P < 0.05 means significantly different.
^dPCOS/non PCOS subgroups compared in the same BMI degree, P < 0.05 means significantly different.
P: PCOS group, non P: non PCOS group, BMI: body mass index, E2: estradiol, T: testosterone, FSH: follicle-stimulating hormone, LH: luteinizing hormone.
