HR: hazard ratio; CI: confidence interval.
aModel 1 was adjusted for age, alcohol consumption, cigarette smoking, community, and, for women, menopausal status at baseline.
bModel 2 was adjusted for factors in Model 1 plus body mass index.
cModel 3 was adjusted for factors in Model 2 plus systolic blood pressure, antihypertensive medication use, diabetes mellitus, and hypercholesterolemia.
