  1. Data presented as ÎČ-value (95 % confidence interval). All analyses have used multivariable linear regression models, and are adjusted for age (continuous), body mass index (continuous), number of children (continuous), previous oral contraceptives (categorical), and current smokers (categorical)
  2. FFQ food frequency questionnaire
  3. aNumbers may vary owing to missing information
  4. bEstimated change in mammographic density per unit increase in the alcohol intake variable
  5. cAlcohol consumption reported in past year, FFQ
  6. dOne drink or unit is equal to 10 g alcohol
  7. eIncludes spirits and fortified wine
  8. fAlcohol consumption reported in last 7 days representing 1 week, food diary
