Table 4 Multivariate logistic regression analysis of factors associated with sustained viral response to interferon-alpha therapy in chronic hepatitis C patients

From: High versus standard doses interferon-alpha in the treatment of naïve chronic hepatitis C patients in Taiwan: a 10-year cohort study

Variable†   Odds ratio 95% CI‡
Pretreatment HCV RNA level§ Per 1 log increase 0.179 0.096–0.336
HCV genotype 1b = 1; non-1b = 0 0.324 0.151–0.695
IFN-α regimen 6-MU = 1; 3-MU = 0¶ 2.310 1.070–4.990
Stage of fibrosis F3–4 = 1; F0–2 = 0 0.408 0.104–0.892
  1. † Factors included, age, sex, history of transfusion, pretreatment serum level of alanine aminotransferase and hepatitis C virus RNA, hepatitis C virus genotype, total necroinflammatory activity score, fibrosis score, interferon preparation, and interferon dose.
  2. ‡ CI: confidence interval.
  3. § HCV: hepatitis C virus.
  4. ¶ 3-MU group: interferon-α 3 million units thrice weekly for 24 weeks; 6-MU group: interferon-α 6 million units thrice weekly for 24 weeks.
