A systematic review is a specific and reproducible method to search, identify, select, appraise, and summarize all studies relevant to a particular health care question. In this paper, we will review the concept of level of evidence, define the terms systematic review and meta-analysis, and outline the steps in performing a systematic review and meta-analysis with an illustrative example. We will also introduce some important concepts in systematic reviews and meta-analyses like heterogeneity, publication bias, forest plots, and quality assessment. Finally, this review will focus on systematic reviews addressing therapeutic research questions.
系统评价是一种特定且可重复的方法，用于检索、识别、选择、评估和总结与特定医疗保健问题相关的所有研究。在本文中，我们将回顾证据水平的概念，定义系统评价和荟萃分析这两个术语，并通过一个示例概述进行系统评价和荟萃分析的步骤。我们还将介绍系统评价和荟萃分析中的一些重要概念，如异质性、发表偏倚、森林图和质量评估。最后，本综述将聚焦于针对治疗性研究问题的系统评价。
