In the Results section, paragraph 1, line 5 (page 155, right column), the correct unit of plasma nitrotyrosine should read µg/l, and the P-value P = NS (instead of µmol/l, P < 0.0001 as stated erroneously). The correct unit and the absence of a significant difference are indicated in Table 2. The authors would like to apologise for this error.
