Magnetic resonance imaging (MRI)-based breast tissue measurements in relation to maternal height and maternal mammographic breast measurements (minimally adjusted estimates). ref Reference category. MRI breast measurements were log-transformed, and exponentiated estimated regression parameters, with 95 % CI calculated by exponentiating the original 95 % CIs, are presented. Models were adjusted for the participant’s age, BMI and menstrual phase/hormonal contraceptive use at the time of MRI and, where appropriate, mother’s age and BMI at mammography. Continuous variables were centred at the mean
