Table 2 GRADE classification method
From: Expert consensus on drug treatment of chronic subdural hematoma
Quality level | Current 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 |
Recommendation level | Â |
 Strong | Benefits clearly outweigh risk, or vice versa |
 Weak | Uncertainty in the estimates of benefits and risks; benefits and risk may be closely balanced |
