NOTE: The odds in brackets represent the number of women with extensive versus the number of those with few densities. ORs (95% CIs) were adjusted for age, body mass index, age at menarche, age at first birth and number of birth combined, use of oral contraceptive, menopausal status and use of hormone replacement, family history of breast cancer, education, smoking status, alcohol, and total caloric intakes. The reference category corresponds to women with daily dietary intakes of vitamin D <100 IU/d and calcium <750 mg/d.
