*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: confidence interval; ED: emergency department; RCT: randomised controlled trial; RR: risk ratio. | ||||||
GRADE Working Group grades of evidence High quality: We are very confident that the true effect lies close to that of the estimate of the effect. Moderate quality: 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 quality: Our confidence in the effect estimate is limited: The true effect may be substantially different from the estimate of the effect. Very low quality: We have very little confidence in the effect estimate: The true effect is likely to be substantially different from the estimate of effect. |
1 Risk of bias: rated 'not serious' (no downgrade) ‐ clear reporting of good methods.
2 Imprecision: rated 'serious' (downgraded by 1) ‐ few events, wide confidence intervals.
3 Indirectness: rated 'serious' (downgraded by 1) ‐ respiratory obstruction proxy measure ‐ not 'death'.
