Table 3 Modified GRADE approach for evaluation of the overall quality of evidence [16]
Quality of evidence | Definition |
|---|---|
High | We are very confident that the true measurement property lies close to that of the estimate of the measurement property |
Moderate | We are moderately confident in the measurement property estimate: the true measurement property is likely to be close to the estimate of the measurement property, but there is a possibility that it is substantially different |
Low | Our confidence in the measurement property estimate is limited: the true measurement property may be substantially different from the estimate of the measurement property |
Very low | We have very little confidence in the measurement property estimate: the true measurement property is likely to be substantially different from the estimate of the measurement property |
