Forest Plot of studies comparing the effect of treatment with peginterferon-alfa-2a vs standard-dose peginterferon-alfa-2b for genotype 1: Peginterferon-alfa-2a showed higher SVR as compared to standard dose of peginterferon-alfa-2b as well: 42.09% versus 33.44% (RR = 1.10, IC 95% 1.01 – 1.20, assuming a fixed-effect framework).
