The Grading of Recommendations Assessment, Development and Evaluation (GRADE)

The aim is to address the shortcomings of grading systems in health care. The working group has developed a common, sensible and transparent approach to grading quality (or certainty) of evidence and strength of recommendation. The aim of the GRADE Working Group is to reduce unnecessary confusion arising from multiple systems for grading evidence and recommendations. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach is the most prominent of the many frameworks developed over the years to assess the quality of evidence, and has been adopted by WHO and many other national and international organizations.
