Fig. 2From: Studying the association between longitudinal mammographic density measurements and breast cancer risk: a joint modelling approachSmoothed average (square root) predicted MD values. Smoothed average (square root) predicted MD values (from model (3)), by age, for women diagnosed with BC at the end of follow-up (with 95% confidence band marked by shading in blue), and for women that remained free from BC diagnosis until the end of follow-up (in black—the confidence band is not represented since it is very narrow, comparable to that based on observed MD values for all women, represented in Fig. 1)Back to article page
