On-treatment predictions of success in peg-interferon/ribavirin treatment using a novel formula

Figure 1 Sustained virological response rates (%) of the patients during peg-interferon plus ribavirin therapy for chronic hepatitis C at week 4 (4 wk), week 12 (12 wk) and week 24 (24 wk). HCV RNA (-) means patients whose serum HCV RNA became undetectable at the time point indicated. HCV RNA (+) means patients whose serum HCV RNA was not cleared at the indicated time point.

Figure 2 Receiver operating characteristic (ROC) curves and the area under curve (AUC) of the predictive values made by the formulae during peg-interferon plus ribavirin therapy for chronic hepatitis C at week 4, 8, 12 and 24.

Figure 3 Receiver operating characteristic (ROC) curves of the predictive values calculated by the formula from data up to 48 wk of peg-interferon plus ribavirin therapy for chronic hepatitis C.
