Estimated effect of circulating levels of testosterone on breast cancer relapse in the different BMI groups of ER-positive postmenopausal breast cancer patients according to Cox proportional hazard regression model for DFS, using testosterone levels as a continuous variable, BMI category, interaction terms between testosterone and BMI, with tumour size and number of metastatic lymph nodes as adjusting covariates. Relapse-specific hazard ratios with pertinent 95% confidence intervals are plotted. First quartile of testosterone level (0.278 ng/mL) is the reference value
