Multivariate logistic regression models, consistent with univariate regression, retained the predictive role of the DHEAS/T ratio against increase in WHR (OR = 0.44;p = 0.016) and of DHEAS against increase in eAG (OR = 0.36;p = 0.029) in the non-PCOS control group. The gene discussed is KCNH1; the disease is polycystic ovary syndrome.
