Sir,

We acknowledge with gratitude the error pointed out in the methodology section of our research article by Ramazani et al., and agree that our study was incorrectly called “case-control.”[1],[2] Such designs begin with a selection of two groups, one with and the other without the outcome of interest. We however do not think that our design should be called a retrospective or histrorical cohort because in such a case, “existing records are used to identify a historical cohort and to measure both exposures and outcomes of interest, all of which have occurred at the time the study is initiated.”[3] We did not follow-up the patients for any period in our study, neither did we make use of records to identify outcomes of interest.

Instead, our study would most accurately called a comparative cross-sectional study which has been defined as “a study of two or more populations to discover the prevalence or incidence of the characteristic in each population.”[4] We compared the prevalence of depression and posttraumatic stress disorder between persons who had a history of involvement in road traffic accidents and those without such a history; the latter who should have been called the “comparison group” not “control group.” We apologize to our readers and ask that our paper should be read and understood in light of these corrections.
