Baseline Characteristics of Study participants (PCOS and control women).

PCOS, polycystic ovary syndrome, based on NIH criteriaPA, physical activity; FAI, free androgen index; tT, total testosterone; SHBG, sex hormone binding globulin; DHEAS, dehydroepiandrosterone sulfate; A4, androstenedione.BMI, body mass index; WC, waist circumference; TC, total cholesterol; LDL-c, low density lipoprotein cholesterol; HDL-c, high density lipoprotein cholesterol; TG, triglycerides; FPG, fasting plasma glucose; 2-h PG, 2-hour glucose; HOMA-IR, insulin resistance calculated by homeostasis model assessment from this formula: (fasting insulin level (mIU/l) × FPG (mmol/l)/ 22.5.IR, insulin resistance; cut-off point for IR = 2.6 (from above formula).HOMA-%β, homeostasis model assessment value for percent β-cell function: [fasting insulin level (mIU/l) × 20 / (FPG (mmol/l) − 3.5)].SBP, systolic blood pressure; DBP, diastolic blood pressure; DM, diabetes mellitus; HTN, hypertension; MetS, metabolic syndromea Data are shown as mean±SD.b Values are expressed as of geometric mean ± SD; measures were analyzed using logarithmic transformation (Ln).c Data shown as percentage.d Significant difference (Pa, b and Fisher’s Exact test for superscript c.e No significant difference was seen in all parameters between 2 groups after adjustment for age and BMI (Analysis of Covariance for superscripts a, b, and Logistic Regression for superscript c), except for tT and SHBG (PBaseline Characteristics of Study participants (PCOS and control women).
