Presence of significant TH cell proliferative response to hepatitis C virus (HCV) antigens in patients with viral clearance (group A) compared with that in patients with viral persistence (group B). (A) Percentage of patients in groups A and B with a significant response to two or more HCV proteins. Numbers above bars are numbers responding/numbers tested. p value was calculated using the χ2 test. (B) Number of patients in each group with a significant response to various numbers of HCV proteins.
