Simple Models: Stratified by time since diagnosis (months), adjusted for age at diagnosis (years) and quintiles of energy intake

Adjusted Models: Stratified by time since diagnosis (months), adjusted for age at diagnosis (years), quintiles of energy intake, body mass index, age at first birth and parity, oral contraceptive use, menopausal status and HRT use, smoking, stage of disease, radiation treatment, chemotherapy and hormonal treatment, and physical activity
