ROC curves for LDL cholesterol, apoB, non-HDL cholesterol, and the total cholesterol–to–HDL cholesterol ratio deciles. ROC curves for LDL cholesterol, apoB, non-HDL cholesterol, and the total cholesterol–to–HDL cholesterol ratio deciles. The area under the ROC curve was 0.685, 0.691, 0.695, and 0.722 for the CVD risk-prediction model with LDL cholesterol, apoB, non-HDL cholesterol, and the ratio of total to HDL cholesterol, respectively. The CVD risk prediction model included age (in 5-year categories), BMI (<23, 23–24, 25–27, 28–30, ≥31 kg/m2, and missing), family history of myocardial infarction (yes or no), physical activity (quartiles), cigarette smoking (never, past, or current), alcohol consumption (0, 0.1–4.9, 5.0–9.9, 10.0–14.9, and ≥15.0 g/day), fasting status (yes or no), history of hypertension (yes or no), aspirin use (yes or no), and HbA1c (quartiles), and LDL cholesterol, apoB, non-HDL cholesterol, or the ratio of total to HDL cholesterol.
