Figure 2From: Low salivary testosterone levels in patients with breast cancer Lines represent regression of testosterone on E2. Cases are plotted as black circles while controls as red. Regression line equation for controls: E2 = 1.002+0.02* Testosterone, R2 = 0.181 p-values 0.235, <0.001 for constant and beta1, respectively. Regression line equation for cases: E2 = 1.212+0.028*Testosterone, R2 = 0.061 p-values <0.001, <0.001 for constant and beta1, respectively. E2, pg/ml, Testosterone, pg/ml.Back to article page
