Quality of evidence | Conventional definition | New definition |
---|---|---|
High | Further research is very unlikely to change our confidence in the estimated effect. | We are very confident that the true effect lies close to that of the estimated effect. |
Moderate | Further research is likely to have an important impact on our confidence in the estimated effect and may change the estimate. | We are moderately confident in the effect estimate: The true effect is likely to be close to the estimated effect, but there is a possibility that it is substantially different. |
Low | Further research is very likely to have an important impact on our confidence in the estimated effect and is likely to change the estimate | Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimated effect. |
Very low | Any estimate of effect is very uncertain. | We have very little confidence in the estimate: The true effect is likely to be substantially different from the estimated effect. |
