In recent years, published systematic reviews in the world and in Iran have been increasing. 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.
近年来，全球和伊朗已发表的系统评价数量一直在增加。这些研究是回答循证临床问题的重要资源，有助于卫生政策制定者和希望找出已发表研究中证据空白的学生。系统评价研究，无论是否进行荟萃分析，都会综合来自针对同一研究问题的研究所获得的所有可用证据。在本研究中，将详细介绍系统评价的步骤，如研究问题的设计与确定、合格已发表研究的检索、与研究问题相关信息的提取与综合以及结果的解读。这将对所有感兴趣的研究人员有所帮助。
