U, unadjusted; 1, Model 1 is adjusted for sex and age, stratified by race and study center. 2, Model 2 in addition adjusted by traditional risk factors: total cholesterol, triglycerides, high density lipoprotein, current smoking, diabetes mellitus, body mass index, leisure activity index, systolic blood pressure, use of blood‐lowering medications, QT‐prolonging drugs, beta‐blockers. 3, Model 3 in addition adjusted by ECG characteristics: heart rate, QRS duration, P duration, P axis, QTc, QRS‐T angle, sex‐specific Cornell product, third degree inter‐atrial conduction block. CHD indicates coronary heart disease; CVD, cardiovascular disease.
