Regression of testosterone on E1. Cases are plotted as black circles while controls as red. Regression line equation for controls: E1 = 4.256+0.012* Testosterone, R2 = 0.003 p-values <0.001, 0.532 for constant and beta1, respectively. Regression line equation for cases: E1 = 3.662+0.046*Testosterone, R2 = 0.025 p-values <0.001, 0.017 for constant and beta1, respectively. E1, pg/ml, Testosterone, pg/ml.
