GRADE在诊断准确性试验系统评价中应用的原理、方法、挑战及发展趋势

Rationales, Methods, Challenges and Development Tendency of Using GRADE in Systematic Reviews of Diagnostic Accuracy Tests

诊断性试验的系统评价按基于原始研究的类型可分为两类:一类是基于诊断性随机对照试验的系统评价,其GRADE分级与干预性系统评价的方法类似;另外一类是基于诊断准确性试验的系统评价,其GRADE分级原理和方法是本文论述的重点。本文主要从理论分析的角度阐述了GRADE在诊断准确性试验系统评价中应用的原理、方法以及挑战。

Depending on different designs of original studies, systematic reviews of diagnostic studies could be cat- egorized into two kinds： one is based on diagnostic randomized controlled trials, of which the GRADE rating approach is similar to that of interventional systematic reviews; and the other is based on diagnostic accuracy tests, of which the GRADE rating approach is introduced in this article. This article explains the application of GRADE in systematic reviews of diagnostic accuracy tests mainly from the angle of theoretical analysis, including rationales, methods, and challenges.
