First paragraph (this article has no abstract)

We wish to report some corrections to our study [1], none of which alters the interpretation of the data or the conclusions drawn. After publication, we noticed that one of the micro-array hybridizations (on sample NB11) was performed on the same patient's material as another hybridization (sample NB4; see Table 1; a corrected version of Table 5 [1]). As this error leads to an incorrect subclassification of the patients into the 'favourable' and 'unfavourable' neuroblastoma subgroups, we would like to exclude this data point from the differential expression analysis of favorable versus unfavorable neuroblastoma given under the heading 'Differential expression analysis of favorable and unfavorable neuroblastoma' in the Results section of [1]. Careful reanalysis after exclusion of NB11 did not lead to important changes in the generated gene lists and conclusions; the changes are given in the corrected paragraph and Table 2 (a corrected version of Table 4 [1]), and the Additional data files 1 and 2 (corrected versions of Additional data files 2 and 3 [1]) available online with this article.
