T total testosterone; SHBG sex hormone binding globulin; FAI free-androgen-index; DHEAS dehydroepiandrosterone sulfate; F-G Ferriman–Gallwey score; HOMA-IR homeostatic model assessment of insulin resistance; LH luteinizing hormone; FSH follicle stimulating hormone; Δ4A Δ4-androstenedione; OR odds ratio; CI confidence interval. P-value was calculated by multivariate logistic regression. Note: The dependent variable represents the number of drops-out at 12 months. The independent variables represent parameters recorded at baseline. *P < 0.05
