Patient or population: children needing dental care
Setting: hospital
Intervention: sedative
Comparison: placebo

VERY LOW1

Very few studies evaluated the same intervention and comparisons. No studies that did evaluate similar interventions and comparisons found the same effect. There is insufficient evidence to draw any conclusions

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

1Downgraded for risk of bias, inconsistency and/or imprecision
