Associations of current smoking compared to never smoking and breast cancer risk by percentiles of absolute predicted 1-year breast cancer risk stratified by alcohol consumption at baseline. Hazard ratios (HR) reflect associations for current smokers compared to never smokers and breast cancer risk by percentiles of absolute predicted 1-year breast cancer risk, as estimated by BOADICEA, stratified by alcohol consumption status at baseline; regular drinkers are presented in panel a and non-regular drinkers in panel b. HRs are stratified by birth cohort and are adjusted for race/ethnicity, study center, education, oral contraceptive use, and body mass index
