This definition was also applied to patients who discontinued treatment early: if the patient had HCV RNA undetected at least 10 weeks after stopping all treatment, they were considered a responder in the primary analysis. This is the primary analyses of the primary endpoint. The number of participants analyzed are actually adjusted number of participant analyzed. |
