OBJECTIVE Data on hepatitis C virus (HCV) viral dynamics and on the effect of interferon in blocking virion production have suggested a rationale for daily administration of interferon in patients with chronic hepatitis C infection. We compared the efficacy and safety of daily interferon alfa-2b in combination with ribavirin with those of interferon alfa-2b three times a week alone or in combination with ribavirin. METHODS We randomly assigned 321 patients with chronic hepatitis C to receive standard-dose interferon alfa-2b alone or in combination with ribavirin for 48 weeks or daily interferon alfa-2b (3 million units per day for 12 weeks then 3 million units three times per week for 24 weeks) and ribavirin (36 week treatment). RESULTS The rate of sustained virologic response (defined as an undetectable serum HCV-RNA level 72 weeks after initiation of treatment) was higher in patients who received combination therapy with three times weekly interferon (51.7%) or daily interferon (46.1%) than in patients who received interferon alone (25%) (P=0.0001 and P=0.002, respectively). Independent predictive factors for sustained virologic response were combination therapy, weight, genotype and viral load. In conclusion, in patients with chronic hepatitis C, combination therapy with induction treatment (daily interferon for 12 weeks) and shorter duration of treatment was not different from combination therapy for 48 weeks without induction treatment. CONCLUSIONS Induction treatment with interferon for 12 weeks and combination therapy for a total duration of 36 weeks could therefore be cost effective.

D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
