  • * Baseline cohort size was determined after specific exclusions (i.e., had a prior cancer diagnosis other than nonmelanoma skin cancer at baseline, had a bilateral oophorectomy before baseline, or had loge-transformed energy intakes beyond 3 SDs from the study-specific loge-transformed mean energy intake of the population).

  • Total calcium and vitamin D intake includes dietary and supplemental sources.

  • Milk: 1 8 oz serving is equivalent to 245 g; hard cheese: 1 oz serving is equivalent to 28 g; cottage cheese: 1 0.5 cups serving is equivalent to 105 g; yogurt: 1 cup serving is equivalent to 227 g; ice cream: 1 0.5 cups serving is equivalent to 66g.

  • § The Canadian National Breast Screening Study and the Netherlands Cohort Study are analyzed as case-cohort studies so the baseline cohort size does not reflect the above exclusions.
