Article selection process. (a) Flow chart of article selection process. (b) Number of publications from 2005 to November 2020. The study initially searched articles published from January 2005 to November 2020 (a). However, after analyzing preliminary data of selected articles, the authors noticed a rapid increase in the number of publications after 2015 (b). Therefore, for this scoping review, the authors decided to restrict the analysis to articles published between 2015 to November 2020.
