The multivariable regression models for percent density (Model 1 and 2) and dense area (Model 3 and 4) and current alcohol difference between sibling-pairs.

Model 1 is adjusted for difference in age at mammogram (continuous) between sibling-pairs.

Model 2 is adjusted for difference in age at mammogram (continuous) and difference in current BMI (continuous) between sibling-pairs.
