The virological response in Koreans infected with HCV genotype 1 did not differ between groups treated with a full dose or reduced dose (≥80 % full dose) of peginterferon alfa-2a: a prospective randomized multicenter trial
A high rate of sustained viral response (SVR) in Koreans with chronic hepatitis C (CHC) is related to a favorable IL28B genotype. We compared two dosing strategies for peginterferon alfa-2a in Koreans with CHC an...
