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

Figure 5 Receiver operating characteristic curves of the chronic liver failure organ failure-acute kidney injury score in the derivation and validation cohorts. A: Derivation cohort; B: Validation cohort. The score demonstrated good discriminative performance for predicting KDIGO stage 3 acute kidney injury within 14 days, with areas under the curve of 0.79 (95% confidence interval: 0.76-0.82) and 0.86 (95%CI: 0.80-0.91), respectively. AUC: Area under the curve; CI: Confidence interval.
