P: compare in the three subgroups.
aE2 > 293.6 pmol/L subgroup compared with 146.8 ≤ E2 ≤ 293.6 pmol/L subgroup, P < 0.05 means significantly different.
bE2 > 293.6 pmol/L subgroup compared with E2 < 146.8 pmol/L subgroup, P < 0.05 means significantly different.
c146.8 ≤ E2 ≤ 293.6 pmol/L subgroup compared with E2 < 146.8 pmol/L subgroup, 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.
