Adjusted for age (continuous), smoking [never, past, or current cigarette use (1–14/d, 15–24/d, ≥25/d, or missing)], alcohol intake (0, <5, 5–15, or >15 g/d), family history (yes or no), physical activity (quintiles), aspirin use (<1, 1–2, 3–6, 7–14, or ≥15/wk), menopausal status and postmenopausal hormone use (premenopausal, never, past, or current hormone use), and history of hypertension and high blood cholesterol. Relative risks were computed from a Cox proportional hazard model.
Additionally adjusted for the Alternate Healthy Eating Index (quintiles).
