*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; RR: Risk ratio
GRADE Working Group grades of evidenceHigh 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 'serious' ‐ method of allocation concealment not stated, blinding of participants uneffective

2 Imprecision: rated 'very serious' ‐ less than 100 patients, 95% CI extends beyond the no effect point

3 Risk of bias: rated 'serious' ‐ method of randomisation is not described, allocation concealment is not stated, single‐blind.

4 Indirectness: rated 'serious' ‐ not threat or injury to self or others, therefore had to use scale derived data for agitation.

5 Risk of bias: rated 'very serious' ‐ allocation of concealment not stated, open trial, adverse effects only reported where they occurred in ≥10% of people, sponsored by drug company.

6 Publication bias: rated 'strongly suspected' ‐ sponsored by drug company.

7 Imprecision: rated 'serious' ‐ 95% confidence intervals are wide.

8 Moderate risk roughly is roughly equal to that of the control group.

9 Indirectness: rated 'serious' ‐ abnormal ECG ‐ not necessarily a serious adverse effect.
