Notes: BMI = body mass index; BSO = bilateral salpingo-oophorectomy; CI = confidence interval; RR = relative risk.
a Numbers and percents reflect those from Adjustment 1 models.
b Adjusted for age (continuous), race (white, non-white), and parity (nominal).
c Adjusted for age (continuous), race (white, non-white), parity (nominal), education (ordinal), age at menarche (nominal), BMI (continuous), pack-years of smoking (continuous), and hormone therapy use (nominal); due to additional adjustments, sample sizes are smaller than in Adjustment 1 models due to missing information.
