Comparison of treatment response between the patient group with a baseline low virological load (LVL; serum hepatitis C virus [HCV] RNA level of 50 IU/mL to less than 600,000 IU/mL) and the group with a baseline high virological load (HVL; serum HCV RNA level of greater than 600,000 IU/mL) using a sensitive real-time polymerase chain reaction assay (Cobas Amplicor HCV monitor, version 2.0, Roche Diagnostics, USA, lower limit of quantitation = 50 IU/mL). ETR End-of-treatment response; SVR Sustained virological response
