At 28 days poor response was defined as </ = 1 log decrease, intermediate 1–3.5 log decrease, marked >3.5 log decrease in viral level. Early virological response was defined as RNA negativity at 12 weeks of therapy. Sustained virological response was defined as RNA negativity at 24 weeks after cessation of therapy.
