Extended-therapy duration for chronic hepatitis C, genotype 1: The long and the short of it

Figure 2 Virologic responses of slow-responders to 48 wk vs 72 wk of therapy. Treatment extension may improve chance of SVR by lessening the chance of relapse. Slow-responders to standard duration therapy (48 wk) may see relapse after an end-of-treatment response is achieved; those receiving extended duration therapy (72 wk) are not as apt to relapse after treatment is completed.
