Multivariable adjusted relative risk estimated from Cox proportional hazards models adjusted for age, ethnicity, and family history of hypertension, smoking status (never smoker, former smoker, current smoker: 1–14, 15–24, or ≥25 cigarettes/d), supplemental folic acid intake, and oral contraceptive use.
