The flowchart illustrates the process of selecting articles for analysis. The process begins with the identification of articles from databases (n = 1298) and other sources (n = 7). After removing duplicates, 602 articles are identified. These articles are then screened by abstracts, resulting in the exclusion of 537 articles. The remaining 65 articles are screened by texts and assessed for eligibility, leading to the exclusion of 33 articles for not meeting criteria. Finally, 32 articles are included in the review.Procedure of selecting articles for analysis. Source: Authors’ own work
