*Serious risk of bias arising from the deviations from intended intervention in all RCTs, high risk of performance bias. Some concerns in other domains.
†Raw data was not available in one study; generic inverse variance meta-analysis of the reported RRs in the studies was performed.
‡Enrolled patients had mostly severe/very severe symptoms. Patients with mild-to-moderate symptoms were missing or underrepresented.
§Moderate risk of confounding and selection bias.
¶Presence of heterogeneity.
**Inconclusive confidence interval.
††Only one study included. Evaluation of inconsistency is not applicable (NA).
‡‡Wide confidence interval.
