Figure 4 The area under the receiver operating characteristic curve and calibration curve of the nomogram for predicting the overall survival of cirrhotic patients with acute kidney injury in the training cohort. A: The area under the receiver operating characteristic curve of the nomogram for mortality at 30-, 90- and 180-d in the training cohort; B: Calibration curve of the nomogram in predicting 30-d overall survival in the training cohort; C: Calibration curve of the nomogram in predicting 90-d overall survival in the training cohort; D: Calibration curve of the nomogram in predicting 180-d overall survival in the training cohort.
