[GRADE guidelines 9.Rating up the quality of evidence].

The most common reason for rating up the quality of evidence is a large effect.GRADE suggests considering rating up quality of evidence one level when methodologically rigorous observational studies show at least a two-fold reduction or increase in risk,and rating up two levels for at least a five-fold reduction or increase in risk.What is GRADE? BMJ Best PracticeAn overall GRADE quality rating can be applied to a body of evidence across outcomes,usually by taking the lowest quality of evidence from all of the outcomes that are critical to decision making.[6] GRADE has four levels of evidence also known as certainty in evidence or quality of evidence very low,low,moderate,and high (Table 1).WHO Box 3.1 Approach to rating the quality of evidence GRADE separates the rating of the quality of evidence from the rating of the strength of the recommendation.The quality of evidence is defined as the confidence that the reported estimates of effect are adequate to support a specific recommendation.

Introducing GRADE a systematic approach to rating

GRADE (Grading of Recommendations Assessment,Development and Evaluation) is a well-developed formal process to rate the quality of scientific evidence in systematic reviews and to develop recommendations in guidelines that are as evidence-based as possible.How to GRADE the quality of the evidenceThe GRADE system rates the quality of evidence for each outcome,from a rating of HIGH to VERY LOW.See section 2.1 for an overview of GRADE and section 3 for additional sources of information.Grading the Quality of Evidence - KTDRRThe end result of the grading process is an evidence summary that can be used by guidelines developers and policy makers.Articles on Grading the Quality of Evidence.Dijkers,M.(2013).Introducing GRADE a systematic approach to rating evidence in systematic reviews and to guideline development.KT Update,1(5).
