Univariate logistic regression models determined unadjusted associations of MetS and its components (elevated central obesity, glucose, blood pressure and triglyceride, and low high-density lipoprotein cholesterol) with PCOS features (log-transformed total testosterone (LTT), sex-hormone binding globulin (LSHBG), amenorrhea, and oral contraceptive pills (OCP) use). The gene discussed is SHBG; the disease is metabolic syndrome.
