Immediate virological response predicts the success of short-term peg-interferon monotherapy for chronic hepatitis C

Figure 1 Administration of peg-interferon (PEG-IFN) α2a. The patients received subcutaneous injections of 180 μg of PEG-IFN α2a (rotundity) once per week. Twenty-one patients (Pts. 1-21) completed a 12-wk treatment course without dose reduction. In 17 patients (Pts. 22-38), the dose was reduced to 90 μg (triangle) or the treatment was terminated before completion of the 12-wk course.
