Critical appraisal of an article published in the Ethiopian Medical Journal

Research involves gathering data, then collating and analyzing it to produce meaningful information. However, not all research is good quality and many studies are biased and their results untrue. Critical appraisal is the process of carefully and systematically examining research to judge its trustworthiness, and its value and relevance in a particular context. This paper attempted to point out the weak and strong points of the study, taking into account sources of bias that were introduced in the article "Visual acuity and road traffic accident (RTA) in Jimma town" published in the Ethiopian Medical Journal.
