Median values are shown. SI: Stimulation index; ns: Not significant; ne: Not evaluated. Differences were considered statistically significant when P < 0.05 (Wilcoxon signed rank test).
Not significant when virological relapsers and non-responders were separately analyzed. a,cIndicate differences between virological responders and non responders, on both evaluation time points (week 48 and week 72) (P < 0.05, Unpaired t test). HCV: Hepatitis C virus.
