Receiver operating characteristic curves (ROCs) and areas under receiver operating characteristic curves (AUROCs).

<p>ROCs and AUROCs for the prediction of the 6-year incidence of hepatocellular carcinoma using sum scores of three risk models: The classical model (Risk Model I, dotted line), the model combining liver-related seromarkers without HBV seromarkers of HBeAg serostatus and serum HBV DNA level (Risk Model II, broken line), and the model combining liver-related seromarkers with HBV seromarkers (Risk Model III, solid line).
