Adjusted for age, state, family history of breast cancer, age at menarche, age at first birth, parity, menopausal status, age at menopause, postmenopausal hormone use, body mass index, education, and total alcohol consumption (minus red or white wine consumption).
For the test of the interaction wine type (red versus white, continuous) P = 0.60.
