A systematic review is an approach to identifying,appraising,and synthesizing research evidence to evaluate and interpret all available research that is relevant to a particular research question.Systematic reviews can be accessed from most databases.Systematic reviews require more rigor and contain less opinion of the author than typical reviews of the literature.An entire journal devoted to research on a clinical problem may be helpful,but it is unknown what type of research is being published in that journal.A well-designed systematic review can provide stronger evidence than a single randomized controlled trial.A researcher alone does not provide the best evidence,rather one would need to look at the information that has been published by the researcher in peer-reviewed journals.
