GRADE Working Group grades of evidence
High certainty: We are very confident that the true effect lies close to that of the estimate of the effect
Moderate certainty: 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 certainty: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect
Very low certainty: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect
CI, confidence interval; NS, not significant; OR, odds ratio; RR, risk ratio
aDowngraded for study limitations (medium risk of bias)
bDowngraded for imprecision
*Three primary outcomes (adverse drug withdrawal events, major adverse cardiac events, and delirium) were not reported
