Model 1 adjusted for age, sex, and race.
Model 2 adjusted for variables in model 1 plus study field center, body mass index, education, smoking status, systolic blood pressure, blood pressure lowering medications, diabetes mellitus, ratio of total cholesterol/high density lipoprotein, use of cholesterol lowering medications, use of aspirin, family history of coronary heart disease and serum creatinine (all at baseline).
