a Distribution of healthy women, women with benign lesions and of breast cancer patients in respect to plasma sTGFβrIII expression levels and age. b Age-adjusted differences in plasma sTGFβrIII expression levels between subject groups (left) and regression coefficients of plasma sTGFβrIII expression level on age across the three subject groups (right: depicted are regression coefficients with 95% confidence interval (CI) and a difference in coefficient between healthy women and breast cancer patients). These effects were obtained in a general linear model with group, age and group*age interaction effects
