Objectives: 

Concise definitive review of how to read and critically appraise a systematic review.

Data Sources: 

None.

Study Selection: 

Current literature describing the conduct, reporting, and appraisal of systematic reviews and meta-analyses.

Data Extraction: 

Best practices for conducting, reporting, and appraising systematic review were summarized.

Data Synthesis: 

A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant original research, and to collect and analyze data from the studies that are included in the review. Critical appraisal methods address both the credibility (quality of conduct) and rate the confidence in the quality of summarized evidence from a systematic review. The A Measurement Tool to Assess Systematic Reviews-2 tool is a widely used practical tool to appraise the conduct of a systematic review. Confidence in estimates of effect is determined by assessing for risk of bias, inconsistency of results, imprecision, indirectness of evidence, and publication bias.

Conclusions: 

Systematic reviews are transparent and reproducible summaries of research and conclusions drawn from them are only as credible and reliable as their development process and the studies which form the systematic review. Applying evidence from a systematic review to patient care considers whether the results can be directly applied, whether all important outcomes have been considered, and if the benefits are worth potential harms and costs.

目标： 

关于如何阅读和批判性评价系统评论的简洁明确的评论。

数据源： 

没有任何。

研究选择： 

当前文献描述了系统评价和荟萃分析的实施、报告和评估。

数据提取： 

总结了进行、报告和评估系统评价的最佳实践。

数据综合： 

系统评价是对明确提出的问题的评价，使用系统和明确的方法来识别、选择和批判性评价相关的原始研究，并收集和分析评价中所包含的研究的数据。批判性评估方法既涉及可信度（行为质量），又评估系统评价总结证据质量的置信度。评估系统评价的测量工具-2 工具是一种广泛使用的实用工具，用于评估系统评价的实施情况。效果估计的置信度是通过评估偏倚风险、结果不一致、不精确性、证据间接性和发表偏倚来确定的。

结论： 

系统评价是对研究的透明且可重复的总结，从中得出的结论的可信度和可靠性取决于其发展过程和构成系统评价的研究。将系统评价的证据应用于患者护理会考虑结果是否可以直接应用，是否考虑了所有重要的结果，以及收益是否值得潜在的危害和成本。
