Pegylated interferon plus ribavirin may leads to higher sustained virological response compared with pegylated interferon alone (low certainty).
It is very uncertain whether pegylated interferon + ribavirin (24 weeks) + initial telepravir (12… changes sustained virological response compared with pegylated interferon (48 weeks) + initial telepravir (12 weeks) +… (very low certainty).
Pegylated interferon alpha‐2a showed no clear difference in sustained virological response 6 months after stopping treatment compared with standard interferon (low certainty).
Standard interferon showed no clear difference in sustained virological response 6 months after stopping treatment compared with placebo or control (moderate certainty).
