Comparison of peg-interferon, ribavirin plus telaprevir vs simeprevir by propensity score matching

Figure 1 Rates of virological response to telaprevir and simeprevir according to serum hepatitis C virus RNA levels before and after adjustment by propensity score matching. Percentages represent the proportion of patients with undetectable serum hepatitis C virus (HCV) RNA levels. Patient numbers are shown in parentheses. P-values were calculated using the χ² test prior to matching and McNemarr’s test after matching. A: Before adjustment. Rates of virological response at 4 and 12 wk after treatment were significantly different between the telaprevir (TVR) group and simeprevir (SMV) group; B: After adjustment. No significant difference in the virological response was observed between the two groups. NS: Not significant.
