Abbreviations: CHD, coronary heart disease; CI, confidence interval; HR, hazard ratio; LDL-C, low-density lipoprotein cholesterol.
a Adjusted for age, sex, race, site, total family income, and educational level.
b Adjusted for the variables in model 1 and body mass index, diabetes, smoking status, family history of coronary heart disease, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol level, aspirin use, and antihypertensive therapy.
c Adjusted for the variables in models 1 and 2 and estimated glomerular filtration rate, macroalbuminuria, microalbuminuria, and coronary artery calcium score.
d Adjusted for the variables in models 1–3 and interim use of lipid-lowering medication.
e P value for interaction was examined for the difference in the associations with high-sensitivity C-reactive protein between the LDL-C <130 mg/dL subcohort and the LDL-C ≥130 mg/dL subcohort.
