Incorporating GRADE in Cochrane Reviews: Feedback from the CEU screening programme.
Assessing the quality of the evidence is an integral part of undertaking a Cochrane Review. GRADE is an established method to help authors rate the quality of evidence and to communicate the key results of systematic reviews to users. Since the start of the CEU review screening programme in September 2013 we have been able to see how GRADE is used to assess and communicate the quality of a body of evidence. We also recognise some important challenges Cochrane Review authors and editorial groups have encountered with implementing GRADE. As a result of this experience we are sharing our thoughts on some of the reviews which highlight four key aspects of bringing GRADE methods and ratings into the text of Cochrane Reviews: 1. Describing methods for assessing the quality of the evidence under the ‘Data collection & analysis’ section of protocols and full reviews. 2. Explaining decisions about the quality of the evidence in reporting of results. 3. Incorporating information about the quality of evidence in the Discussion. 4. Drawing on quality of evidence ratings when summarising and interpreting the results e.g. abstracts, plain language summaries and implications for practice sections (read more).
GRADEpro GDT (Guideline Development Tool) is the tool used to create Summary of Findings Tables for Cochrane systematic reviews. You can access the online version and download the App for offline use at www.gradepro.org
