Abstract

Dear Editor-in-Chief of Iranian Journal of Emergency Medicine

In volume 5 of the journal (2018), a paper was published titled "Comparison of Liquid Tissue Adhesive and Suture in Pediatric Wound Repair; a Case Control Study", about which some points and questions should be raised:

1. In the title and methods section of this paper, the authors stated that this study is a "case control study", while case-control studies are a type of observational study, which start with the outcome and end with exposure; as patients (as case group) and non-patients (as control group) will be questioned or examined regarding previous exposure. In addition, since they are observational, no interventions are performed in this type of study.
