The Nurses’ Health Study was broken into two study periods (1980-June 1996 and July 1996–2010) because the follow-up was nearly twice as long as any other study. We updated the exposures in 1996 for that follow-up period.

This cohort was included as a case-cohort design, reflecting a total cohort population of 62,573 women. Appropriate weights for subcohort selection were applied in all analyses.

The percent of cases with missing tumor dominance data ranged from 17.9% in Sister Study to 78.9% in Swedish Mammography Cohort Study
