Stratification by selected breast cancer risk factors. The CECILE study, France, 2005–2007.
P trend determined from the model using the median value in each quartile as a quantitative variable.
Odds ratios adjusted for study area, age at reference date, history of benign breast, family history of breast cancer in first-degree relatives, age at menarche, parity, age at first full-term pregnancy, breast feeding, menopausal status, current use of hormone therapy, oral contraceptive use and body mass index.
No adjustment on the stratification variable.
