Individuals were considered to be free of CHD if they did not have a self-reported history of CHD (myocardial infarction, percutaneous coronary intervention, or coronary artery bypass graft surgery) or evidence of myocardial infarction on their enrollment electrocardiogram.
For this analysis, we calculated 10-Year Framingham Risk Scores for CHD death or myocardial infarction using diabetes as a risk factor for CAD as published by Wilson et al.32
For this analysis, we considered diabetes to be a CAD risk equivalent as recommended by ATP III4, and assumed that all diabetics had a 10-Year Framingham Risk for CHD death or myocardial infarction of >20%.
