[dagger] Adjusted for socioeconomic status, age, height, body mass index (except in body mass index specific analysis), smoking status, history of breast cancer in mother or sister, age at menarche, parity status (except in parity specific analysis), all at baseline; adjusted for age at last known menstruation and menopausal status during follow-up (except for outcome of premenopausal or postmenopausal breast cancer). |
