Liver stiffness at baseline as a marker of hepatocellular carcinoma in cirrhosis: A matched analysis

Figure 1 Receiver operating characteristic curve demonstrating the discriminatory performance of liver stiffness measurement for identifying hepatocellular carcinoma. The area under the receiver operating characteristic curve is shown along with corresponding sensitivity and specificity at selected thresholds. Prevalence-dependent measures are not emphasized given the case–control design. Area under the curve = 0.88 (95%CI: 0.84-0.93). The optimal threshold by Youden’s index was 47 kPa. The diagonal line denotes the no-discrimination reference. ROC: Receiver operating characteristic; AUC: Area under the curve.
