Low quality: further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: we are very uncertain about the estimate.

aDowngraded by two levels for very serious risk of bias; inadequate randomisation or allocation concealment and no evidence of blinding.

bDowngraded by one level for serious imprecision.
