Analysis: Univariate and multivariate analysis will be used to determine factors associated with final endpoints. Subgroup analyses will be done based on time to early virologic response and duration of therapy each stratification. The primary and secondary endpoints will be determined on an intention-to-treat basis starting with all patients that receive at least one dose of study medications. The primary and secondary endpoints will also be determined in a per-protocol analysis on those patients who take 80% of the prescribed CIFN and 80% of the prescribed ribavirin for 80% of the time.
