Hepatitis C virus NS5A region mutation in chronic hepatitis C genotype 1 patients who are non-responders to two or more treatments and its relationship with response to a new treatment

Figure 3 Relationship between sustained virological response and number of baseline mutations in the interferon-sensitivity-determining region of NS5A. The number of baseline mutations in the interferon-sensitivity-determining region is based on the criteria of Enomoto et al[19]. Comparisons between groups were made using χ² tests. SVR: Sustained virological response; NVR: No virological response.
