Table 2 Grades of evidence according to GRADE and their definitions
Grade | Definition |
|---|---|
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. |
