Figure 1. Serum Peginterferon alfa-2a concentrations.

Figure 1

Serum peginterferon concentrations were measured by enzyme-linked immunoassay in patients infected with HCV genotype 1 as described in Materials and Methods. Results expressed as median ± interquartile range (IQR). The numbers of observations at each time point ranged between 141 and 153 for AA and 157 and 168 for CA, except for day 3 (AA = 40; CA = 51). Results were compared between AA and CA using the Wilcoxon rank-sum test.
