^*denotes that hazards ratios from competing model obtained using the method of Fine and Gray

All hazards ratios adjusted for age, race, systolic blood pressure, total and HDL cholesterol, smoking status, and diabetes

CAC = coronary artery calcium; CHD/NFMI = coronary heart disease/nonfatal myocardial infarction; CVD = cardiovascular disease
