In the May 2006 article “Duration of Peginterferon Therapy in Acute Hepatitis C: A Randomized Trial” by Kamal et al. (pages 923-931), the sentence in the middle of the first column on page 927 should read as follows:

The difference in SVR rates between groups A and C was statistically significant (absolute difference, 23.6%; 95% CI of difference 17%-34%; P = .001) while the difference between groups A and B (absolute difference, 14.8%; 95% CI) was not significant (difference 12%-38%; P = .104).

Table 2 on page 927 and Fig. 2 on page 928 have also been modified:
