*Cut-off values were derived from the sensitivity and specificity analysis of the receiver operating characteristic curve.
†Categories of insulin resistance based on normal values used for HOMA-insulin resistance.
‡Cut-off values from normal laboratory reference ranges for Free Androgen Index.
CRP, C reactive protein; HOMA, homeostasis model assessment; PCOS, polycystic ovary syndrome.
