CLIF-AKI score predicts KDIGO stage 3 acute kidney injury in intensive care unit patients with acute-on-chronic liver failure

Figure 8 Receiver operating characteristic curves comparing the performance of the chronic liver failure organ failure-acute kidney injury score with that of the PIRO, Child-Turcotte-Pugh, chronic liver failure consortium acute-on-chronic liver failure, model for end-stage liver disease, and model for end-stage liver disease-sodium scores in the external validation cohort. The curves illustrate the ability of each model to predict KDIGO stage 3 acute kidney injury within 14 days of intensive care unit admission. The area under the curve for each model is indicated in the figure. CLIF-AKI: Chronic liver failure organ failure-acute kidney injury; CTP: Child-Turcotte-Pugh; CLIF-C-ACLF: Chronic liver failure consortium acute-on-chronic liver failure; MELD: Model for end-stage liver disease; MELD-Na: Model for end-stage liver disease-sodium; AUC: Area under the curve.
