To the Editor A publication in JAMA Pediatrics1 has a technical issue that has unfortunately become too common in biomedical journals: the failure to present both adjusted and unadjusted results.

In the case of this particular data set, being able to view the unadjusted results assumes even greater importance because most of the numerous adjustment factors are not specified in the current publication nor in a prior publication of the authors cited by them. Adjusting for “indicators for 50 states”1 (Table 1 footnotes) is an unacceptably vague descriptor for a scientific publication. In an ideal world, the reader would be given enough information to ascertain the specific adjustment factors that had the most impact in modifying the outcome.
