(B, C) Comparison of changes in the expression level of STAT1+ (B) and pSTAT1 (C) NK cells during the first 24 h of therapy in patients who were non-responders to a full course of PegIFN/RBV therapy but had an SVR during a subsequent course of QUAD therapy.
(D) Comparison of changes in the percentage of pSTAT1+ NK cells during the first 24 h of therapy in patients who were non-responders to a full course of PegIFN/RBV therapy but had an SVR during a subsequent course of QUAD therapy.
