Model 1: adjusted for age, sex, and race. Model 2: adjusted for covariates in model 1 plus smoking status, body mass index, history of hypertension, diabetes and cardiovascular disease, eGFR, serum hemoglobin, serum albumin, and Homocysteine in Kidney and ESRD randomized assignment. Q, quartile; 95% CI, 95% confidence interval.
