Data are hazard ratio (95% CI). Model 1 unadjusted. Model 2 adjusted for sex. Model 3 adjusted for age, sex. Model 4 adjusted for model 3 covariates plus ethnicity, family income-poverty ratio level, education, and marital status. Model 5 adjusted for model 4 covariates plus smoking status, diabetes, hypertension, CVD, and CKD. HR, hazard ratio; CI, confidence interval; CDAI, composite dietary antioxidant index; CVD, cardiovascular disease; CKD, chronic kidney disease.
