Identifying relevant studies
We systematically searched Embase, Medline, Web of Science, Cochrane,
CINAHL, and Google Scholar to find relevant studies (updated until
February 2021). No filter was used on date range. Only English articles
were searched. Since the search string was built for a scoping review,
it was construed as broadly as possible so as not to miss any relevant
literature. The electronic search strategies can be found in Table 1.
Additionally, we searched the reference lists of the sources that were
included after full-text screening for relevant studies.
