In the article "Recent Trends in Stimulant Medication Use Among U.S. Children" (Am J Psychiatry 2006; 163:579–585), the column headings in Table 2 were mislabeled. The data for "Number of users" are Ns and 95% CIs, and the data for "Percent with use" are %s and 95% CIs. Also, this article was published as a Review and Overview but in fact contained original data and was submitted as a research paper and not a review.
