Prediction of Esophageal Varices in Viral Hepatitis C Cirrhosis: Performance of Combined Ultrasonography and Clinical Predictors

Figure 6

The receiver operating characteristic (ROC) curve shows the diagnostic accuracy of combined predictors for diagnosing esophageal varices (EV) compared to isolated parameters. The area under the curve (AUROC) for the combined predictor model was 0.80 (95% CI 0.69-0.91), indicating good diagnostic accuracy, while the AUROC for isolated parameters ranged from 0.62 to 0.65.
