The flow diagram is titled “Identification of studies via databases”. On the left side, three vertical labels indicate stages: “Identification”, “Screening”, and “Included”. Under “Identification”, a rectangular box states “Records identified from databases (n equals 711)”. Below it, the sources are listed as “Scopus (n equals 467)” and “Web of Science (n equals 244)”. A horizontal arrow points to a box on the right labeled “Records removed before screening”, which lists “Not articles (n equals 398)”, “Not written in English (n equals 1)”, and “Duplicates (n equals 119)”. Under “Screening”, a downward arrow from the initial records box leads to “Articles screened (n equals 198)”. A horizontal arrow from this box points to “Articles excluded after title and abstract reading (n equals 54)”. A downward arrow leads to “Articles assessed for eligibility (n equals 139)”. A horizontal arrow from this box points to “Articles excluded after full reading (n equals 12)”, with subcategories “Out of A I E D scope (n equals 10)” and “Insufficient discussion (n equals 2)”. Under “Included”, a final downward arrow leads to the box labeled “Articles included in review (n equals 127)”.PRISMA flow diagram. Source(s): Adapted by the authors (2025) according to Page et al.
