The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of overall duration of treatment on SVR. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of duration of treatment after achieving RVR (>18 weeks versus <=18 weeks) on SVR. RVR was defined as HCV RNA <=25 IU/mL at Week 4 using CAP/CTM test. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of duration of treatment after achieving cEVR (>11 weeks versus <=11 weeks) on SVR. cEVR was defined as HCV RNA <=25 IU/mL at Week 12, but not at Week 4 using CAP/CTM test. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of cumulative doses of pegylated interferon alfa-2a on SVR. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of cumulative doses of ribavirin on SVR. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

RVR was defined as HCV RNA less than or equal to (<=) 25 IU/mL at Week 4 using CAP/CTM test. The percentage of participants with probability that the participant who develops RVR would achieve SVR was termed as PPV of RVR on SVR. SVR was defined as HCV RNA level undetectable (<15 IU/mL) 24 weeks after completion of the actual treatment period (measured using CAP/ CTM test).

Analysis population included all treated participants. Here, 'Number of Participants Analyzed' = participants evaluable for this outcome measure.

cEVR was defined as HCV RNA <=25 IU/mL at Week 12, but not at Week 4 using CAP/CTM test.

The viral response development was assessed using univariate analysis with logistic regression model to calculate OR for impact of age (greater than [>] 42 years versus <=42 years) on SVR.
