Data collection
The reviewers screened, titles, abstracts, and reviewed full texts of potentially eligible records using Covidence systematic review software (Veritas Health Innovation, Melbourne, Australia). The data were extracted using standardized forms in duplicate by two reviewers independently. Any conflicts were resolved by a third reviewer and consensus of the task force core team (CR, IS, GdT, AFS). Where relevant information was missing from a study that was potentially eligible for the SR, the corresponding author of the respective study was contacted and inclusion of this study was contingent on completion of this information by email from the corresponding author.
