Theoretical hepatitis C virus viral load, hepatitis C virus-specific cytotoxic T lymphocyte frequency and activated natural Killer cell frequency kinetics during anti-hepatitis C virus treatment with interferon-free and interferon-containing regimes, according to the different types of response. PegIFN: Pegylated-a2-interferon; RBV: Ribavirin; DAA: Direct acting antiviral; NK: Natural Killer cell; CTL: Cytotoxic T lymphocyte; HCV: Hepatitis C virus; RVR: Rapid viral response; EVR: Early viral response; ETR: End of treatment response; SVR: Sustained viral response.
