AKI = acute kidney injury, AKI-sCr = AKI based on creatinine criteria only, AKI-UO = AKI based on urine output criteria only. Statistical significance of comparison of ICU mortality in AKI-sCr versus AKI-UO stages: AKI stage 0: p = 0.002; AKI stage 1: p < 0.001; AKI stage 2: p = 0.001; AKI stage 3: p = 0.070
