The search was performed in six electronic databases (Embase, LILACS, Medline, PubMed, Web of Science and Abstracts in Social Gerodontology) and grey literature (Google Scholar) for articles published up to February 2019. The methodology of selected studies was evaluated using the Meta\u2010Analysis of Statistics Assessment and Review (MAStARI) risk of bias checklist.
