| 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. | ||||
aOverall, studies contributing to this analysis had limitations regarding risk of bias sufficient to lower certainty regarding the estimate of effect and were downgraded once.
bDowngraded twice for serious imprecision (very small numbers of participants).
cDowngraded once for indirectness. Studies included only participants with recent‐onset stroke.
dDowngraded once for indirectness. Studies used different interventions or measured outcomes using different scales.
