^† Per 1,000 person-years. ^‡ Adjusted for age, gender, marital status, smoking, alcohol consumption, physical activity, RHR, SBP, DBP, and TC levels. SBP: systolic blood pressure; DBP: diastolic blood pressure; RHR: resting heart rate; TC: total cholesterol; BMI: body mass index; WC: waist circumference.
