*High levels included individuals in the highest sample-based quartile (CRP > 0.51 mg/dL; WBC > cells/L). Model I adjusts for age, sex, and current BMI. Model II adjusts for current smoking status and total cholesterol in addition to Model I covariates. OR: odds ratio; CI: confidence interval. Bold indicates significant at the .05 level.
