Text: After adjustment for age, sex, racial origin, body mass index, diabetes, and cardiovascular disease, no significant differences in survival were observed between estimated GFR tertiles determined by Cockcroft and Gault (lowest tertile adjusted hazard ratio, 1. 11 ; 95 % confidence interval, 0. 82 to 1. 49 ; middle tertile hazard ratio, 1. 29 ; 95 % confidence interval, 0. 96 to 1. 74 ; highest tertile reference), Modification of Diet in Renal Disease (lowest tertile hazard ratio, 0. 88 ; 95 % confidence interval, 0. 63 to 1. 24 ; middle tertile hazard ratio, 1. 20 ; 95 % confidence interval, 0. 90 to 1. 61 ; highest tertile reference), and Chronic Kidney Disease-Epidemiology Collaboration equations (lowest tertile hazard ratio, 0. 93 ; 95 % confidence interval, 0. 67 to 1. 27 ; middle tertile hazard ratio, 1. 15 ; 95 % confidence interval, 0. 86 to 1. 54 ; highest tertile reference).
