Comparison of SVR and non-SVR patients treated with peginterferon, ribavirin, and telaprevir by univariate analysis (a) and multivariate analysis (b).
(a) Univariate analysis |
| | SVR, | Non-SVR, | values (SVR versus non-SVR groups) |
| Gender, male/female | 24/8 | 5/2 | 0.77 | Age, years | 57.8 ± 9.3 | 59.8 ± 5.6 | 0.58 | Previous treatment: naïve/relapse/null | 14/17/1 | 3/2/2 | 0.13 | AST, IU/L | 55.9 ± 50.1 | 44.7 ± 16.0 | 0.56 | ALT, IU/L | 71.9 ± 70.6 | 51.1 ± 19.9 | 0.44 | γ-GTP, IU/L | 62.1 ± 64.7 | 46.2 ± 27.9 | 0.53 | Hemoglobin, g/dL | 14.6 ± 1.3 | 14.4 ± 1.6 | 0.72 | Platelets, ×104/mm3 | 16.4 ± 5.2 | 14.3 ± 4.6 | 0.33 | HCV RNA () | 6.45 ± 0.68 | 6.81 ± 0.75 | 0.220 | Treatment response | | | | RVR, | 27 | 0 | <0.0001 | EVR, | 32 | 2 | <0.0001 | IFNL4, major/minor/ND | 22/8/2 | 2/5/0 | 0.0727 |

Null: null response; AST: aspirate aminotransferase; ALT: alanine aminotransferase; γ-GTP: γ-glutamyltransferase; RVR: rapid virological response; EVR: early virological response; SVR: sustained virological response.

(b) Factors associated with SVR among patients treated with peginterferon, ribavirin, and telaprevir by multivariate analysis |
| Factor | Category | Odds ratio | 95% CI | values |
| HCV RNA (log IU/mL) | <6.4/6.4≤ | 13.74 | 1.014–186.30 | 0.048 | IFNL4 ss469415590 | major/minor | 17.54 | 1.980–156.25 | 0.010 |
