Grading of the quality of evidence | |
High ⨁⨁⨁⨁ | We are very confident that the true effect lies close to that of the estimate of the effect |
Moderate ⨁⨁⨁○ | We are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different |
Low ⨁⨁○○ | Our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect |
Very low ⨁○○○ | We have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect |
Strength of the recommendation | |
