Distribution of RIFLE class based on a single or both criteria. Based on the urinary and the creatinine criteria together (AKIboth), 35.5% of patients had no AKI, versus 20.6%, 31.8%, and 12.1% with RIFLE R, I, and F. Based on the urinary output criterion only (AKIuo), 58.9% patients were classified as having no-AKI, versus 10.3%, 27.1%, and 3.7% as RIFLE-R, I, or F, respectively. Based on the creatinine criterion only (AKIc), 57% had no AKI, versus 17.8%, 15%, and 10.3% classified as RIFLE R, I, and F (P < 0.03).
