In the article entitled “Opsoclonus-Ataxia Caused by Childhood Neuroblastoma: Developmental and Neurologic Sequelae,” by Mitchell et al published in the January 2002 issue of Pediatrics (2002;109:86–98), one of the tables listed scores of a number of motor tests. We recently found several errors in calculating and transcribing the scores. In addition, we cannot confirm that the modified scoring procedure (done to avoid truncating the lower range of scores) was done correctly, so we need to go with the new scores, which truncate the lowest scores at −3.0 z score. None of this affects the conclusions of our article, but there are substantial inaccuracies in Table 4.
A revised version of Table 4 appears on page 854 of this issue.
