A Study of Predictors of the Effectiveness of Pegylated Interferon in a Cohort of Participants With Hepatitis C

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. 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 gender (male versus female) 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 body weight 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 baseline level of fibrosis on SVR. Level of fibrosis was measured in terms of kilopascals (kPa) using elastography. kPa score was categorized in 4 groups: 0 to 6.0; 6.1 to 9.9; 10.0 to 14.5; and 14.6 and above. 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 baseline ALT level (>40 international units per liter [IU/L] versus <=40 IU/L) 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 baseline viral load count (>800000 IU/mL versus <=800000 IU/mL) 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 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).
