The protocol for this systematic review has been published on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42020215904). Search results were imported into Covidence software (Veritas Health Innovation, n.d.) and all stages of screening and data extraction were completed on that platform. Each eligible study was screened, at both the title/abstract and full text screening stages, by two independent reviewers (from a team of ten reviewers). Conflicts were resolved by the lead reviewers (ES, LPS), who had an inter-rater agreement of more than 94%.
