Interpretation of strong and conditional recommendations for an intervention
Audience |
Strong recommendation |
Conditional recommendation |
Patients |

Most individuals in this situation would want the suggested course of action, but many would not |

(GRADE Working Group 2013)
Grade |
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 |
