From: A comparison of different diagnostic criteria of acute kidney injury in critically ill patients
Area under the curves for RIFLE, AKIN, and KDIGO classification schemes comparing the predictive ability of RIFLE, AKIN, and KDIGO classification schemes for in-hospital mortality. AKIN, Acute Kidney Injury Network; KDIGO, Kidney Disease: Improving Global Outcomes; RIFLE, Risk, Injury, Failure, Loss of Kidney Function, and End-stage Kidney Disease; ROC, receiver operating characteristic.
RIFLE: Area Under the Curve 0.738 (95% CI 0.713-0.762, P < 0.001).
AKIN: Area Under the Curve 0.746 (95% CI 0.721-0.770, P < 0.001).
KDIGO: Area Under the Curve 0.757 (95% CI 0.733-0.780, P < 0.001.
