Systematic reviews and meta-analyses form a secondary research methodology that identifies and critically appraises all the relevant studies that are available in various databases to answer a particular research question in an unbiased and systematic manner. In the pyramid of level of evidence, the systematic review of high-quality studies is placed at the highest hierarchy position. Meta-analysis is the statistical analysis of the systematic review that provides pooled estimates of the effect of individual studies in the systematic review, but sometimes a meta-analysis may not always be possible. This article elaborates the key steps to conduct a high-quality systematic review and meta-analysis in the field of radiology and intervention radiology, which will help the readers to design and conduct them along with to understand and interpret this secondary research.
系统评价和荟萃分析构成了一种二次研究方法，该方法以无偏且系统的方式识别并严格评估各种数据库中所有可用的相关研究，以回答特定的研究问题。在证据等级金字塔中，高质量研究的系统评价处于最高层级。荟萃分析是对系统评价的统计分析，它提供了系统评价中各项独立研究效应的合并估计值，但有时荟萃分析并非总是可行。本文阐述了在放射学和介入放射学领域进行高质量系统评价和荟萃分析的关键步骤，这将有助于读者设计和开展此类研究，同时理解和解读这种二次研究。
