Table 3 Modified GRADE approach for evaluation of the overall quality of evidence [16]

From: Performance properties of health-related measurement instruments in whiplash: systematic review protocol

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
