These studies are an important resource to answer evidence‑based clinical questions and assist health policy‑makers and students who want to identify evidence gaps in published research. Systematic review studies, with or without meta‑analysis, synthesize all available evidence from studies focused on the same research question. In this study, the steps for a systematic review such as research question design and identification, the search for qualified published studies, the extraction and synthesis of information that pertain to the research question, and interpretation of the results are presented in details. This will be helpful to all interested researchers.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2438http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2438/717718277
