Fig. 4From: Polygenic risk score phenome-wide association study reveals an association between endometriosis and testosteroneCausal relationships between testosterone, endometriosis and clear cell carcinoma ovarian cancer determined by Mendelian randomisation. A causal effect of testosterone and bioavailable testosterone on endometriosis is supported by multiple methods. A causal effect of bioavailable testosterone on clear cell carcinoma ovarian cancer was identified using univariate approaches, but adjustment for endometriosis using multivariable MR attenuated the effect and it was non-significant.
