Text: Compared with a GFR higher than 50 mL/min/1. 73 m (2), after multivariable adjustment, the hazard ratio (HR) for hyperkalemia in patients with a GFR between 31 and 40 mL/min/1. 73 m (2) and a GFR lower than 30 mL/min/1. 73 m (2) was 3. 61 (95 % confidence interval [CI], 1. 42-9. 18 [P =. 007]) and 6. 81 (95 % CI, 2. 67-17. 35 [P <. 001]), respectively ; there was no increased risk of hyperkalemia if GFR was 41 to 50 mL/min/1. 73 m (2).
