When using ROC analyses to explore the ability of serum concentrations of AMH and other endocrine parameters to distinguish women with PCOS from women without PCOS, the area under the curve (ROCAUC) was 0.770 (95% CI, 0.700–0.840) for fT and 0.701 (95% CI, 0.622–0.780) for AMH (Fig. 3). The gene discussed is AMH; the disease is polycystic ovary syndrome.
