From: Hormonal determinants of mammographic density and density change
Relative differences in baseline mammographic density (cm2) (mean and 95% CI), by tertiles of baseline endogenous plasma hormones at study entry with the lowest tertile (Q1) as reference. a Progestogens. b Androgens. c Oestrogens. d Corticoids. e Peptide hormones/proteins. Vertical lines represent the median dense area in the entire population (18.5 cm2). Models are adjusted for age and BMI at baseline, time of day of blood draw and plasma sample plate number. Two-sided P values for the trend of baseline dense area (cm2) at blood collection as a dependent continuous variable across tertiles of hormones
