Figure 1
The flowchart shows four vertical text boxes representing four stages, arranged in a vertical series on the left. From top to bottom, these are labeled: “Identification,” “Screening,” “Eligibility,” and “Included.” In the “Identification” stage, there are two text boxes that read “Records identified through database search (Scopus) n equals 254” and “Records identified through database search (W O S) n equals 300.” From these two boxes, a downward arrow arises, and the arrows merge and point to a text box labeled “Total records n equals 554” in the same “Identification” stage. From “Total records n equals 554,” a downward arrow arises and points to a text box labeled “Records screened n equals 88” in the “Screening” stage. From “Records screened n equals 88,” two right-pointing arrows arise and point to two boxes arranged vertically. The labels from top to bottom are “Records excluded (unrelated to our topic) n equals 430” and “Records after duplicates removed n equals 36.” From “Records screened n equals 88,” a downward arrow arises and points to a box labeled “Full articles assessed for eligibility n equals 88” in the “Eligibility” section. From “Full articles assessed for eligibility n equals 88,” a downward arrow arises and points to a box labeled “Articles included in system review n equals 88” in the “Included” section.PRISMA diagram.
