Table 1 Grades and definitions of evidence quality in CPGs [1]
Evidence certainty | Definition |
|---|---|
A: High | We are very sure that the true effect is close to the estimated effect value. |
B: Moderate | We have a moderate level of confidence in the estimated effect value. In other words, we cannot rule out the possibility that they may be very different. |
C: Low | Our confidence in the estimated effect value is limited. The true and estimated effects may be very different. |
D: Very low | We can hold almost no confidence in the estimated effect value. We believe the true effect differs greatly from the estimated effect. |
