Description: Participants underwent blood sampling at the Study Visit to determine IL28B genotype. HCV RNA genotype and virological response to prior treatment were obtained from medical records. Virological response types within the first 12 weeks of treatment included rapid virological response (RVR), complete early virological response (cEVR), and partial early virological response (pEVR). RVR was defined as an undetectable HCV RNA level within the first 4 weeks, cEVR as an undetectable level within the first 12 weeks, and pEVR as a 2-log drop from Baseline to 12 weeks. Undetectable viral loads include those below the lower limit of detection (LLOD) for the assay performed, which may vary from site to site. Response categories were mutually exclusive, meaning participants could only achieve cEVR/pEVR in the absence of RVR. Participants achieving neither RVR nor cEVR/pEVR were recorded as 'none of the above.'

Undetectable viral loads include those below the LLOD for the assay performed, which may vary from site to site. Response categories were mutually exclusive. Participants with detectable HCV RNA level at 12 or more treatment measurements and who did not meet SVR criteria were considered nonresponders, and those with insufficient treatment response data were recorded as 'none of the above.'
