I read with interest the article by Kang et al,1 in which they reviewed the literature to summarize current evidence about spinal cord injury worldwide. Although the topic is interesting and important, some considerations of their review design are discussed. First, the authors have searched Embase, PubMed, Medline, and Web of Science. Although these databases index many of the published research, there are also other databases that should be considered. For example, Index Medicus for the Eastern Mediterranean Region (IMEMR) and African Index Medicus contain articles published in journals that are not indexed in some of these main databases. This affects the review’s ability to screen all available evidence in order to end up with a more accurate and sound summary of the literature. Also, this may lead to some limitations (database bias).2
