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

Table 2 Influence of the type of previous response on the sustained virological response to a subsequent treatment n (%)

Previous response	NVR, n = 46	SVR, n = 32	OR (95%CI)	P value
Relapse	7 (30)	16 (70)	6.09 (2.0-18.4)	0.006
Partial response viral	7 (64)	4 (36)	1.5 (0.3-6.1)	n.s.
Null response	32 (73)	12 (27)	1

This analysis excluded previous treatments for which the reason for non-response was unknown (n = 51). NVR: No virological response; SVR: Sustained virological response.
