To the Editor We write to alert readers that there are areas of overlap between 2 articles that we published, one in the Archives of Surgery1 and the other in the Journal of Pediatric Surgery.2 Both of these studies used the US National Trauma Data Bank and similar methods of analysis. However, our study in the Archives of Surgery focused on adult patients, whereas our study in the Journal of Pediatric Surgery focused on pediatric patients, and therefore different nonoverlapping subsets of the data bank were used for each study. Given the different analyses and target audiences, we decided to submit them to separate journals. In our Archives of Surgery article,1 we should have included a reference to the previously published article in the Journal of Pediatric Surgery,2 which was accepted and published first. In addition, we should have recognized that the descriptions in the Results and Comment sections of both articles needed to be clearly nonduplicative. We apologize for these important errors.
