Figure 2
The figure consists of a flowchart with three vertical rectangular boxes, stacked and labeled on the left from top to bottom as “Identification”, “Screening”, and “Included”. In the “Identification” phase, a central rectangular box is labeled “Records identified from Scopus (n equals 103)”. A downward arrow points from this box to the first rectangular box in the “Screening” phase, labeled “Records titles and abstracts screened (n equals 103)”. From this box, a horizontal rightward arrow points to a box on the right labeled “Records excluded:” followed by two bullet points: “Different languages (n equals 2)” and “Thesis or reports or books (n equals 16)”. A downward arrow points from the “Records titles and abstracts screened (n equals 103)” box to a second rectangular box in the “Screening” phase labeled “Records assessed for eligibility (n equals 85)”. From this box, a horizontal rightward arrow points to a box on the right labeled “Records excluded:” followed by a single bullet point: “Not accessible (n equals 3)”. A downward arrow points from the “Records assessed for eligibility (n equals 85)” box to the final box in the “Included” phase labeled “Articles included in review (n equals 82)”.Refinement process based on the PRISMA guideline.
