        • GRADE Guidelines: 2. Framing the Question and Deciding on Important Outcomes△

          GRADE要求明確說明相關的背景、人群、干預措施和對照,同時要求不論研究結果能否形成證據,均需詳述所有重要結果。對某一特定管理問題,人群、干預措施及結果應在不同研究間足夠類似,才能認為得到相似的效應量合乎情理。指南制定者在收集證據前應先詳細說明各結局的相對重要性,同樣地,證據總結完成時也需要詳細說明這一點。考慮到替代結局的重要性,對采用替代指標描述且對患者很重要的結局,作者應評估其重要性,并進而降低這種間接結果的證據質量等級。
