Table 4 Comparison of predictive power of a log 10 decrease in HCVcAg at 144 h and rapid virological response (RVR)/early virological response (EVR)

From: Hepatitis C virus core antigen, an earlier and stronger predictor on sustained virological response in patients with genotype 1 HCV infection

  Sensitivity Specificity Accuracy PPV NPV
∆HCV Ag ≥ 1 log 0.952 0.727 0.875 0.870 0.889
RVR 0.286 1.000 0.531 1.000 0.423
EVR 1.000 0.273 0.750 0.724 1.000
