"PubMed, EMBASE, Web of Science, Google Scholar and Scopus were searched using a priori search criteria for articles published between January 1st, 2020 and August 1st, 2021. An effort was made to account for plurals, acronyms, and synonyms. The search was not limited by language. These results then were reviewed by the research team for eligibility. Covidence©, Cochrane's online systematic review platform, was used to streamline the review process. All articles that met the inclusion criteria were retrieved and the full text reviewed. References of included papers were screened for additional studies. The detailed search strategy can be found in Appendix 1. The study protocol was registered (22/06/2021) with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021254647)."
