Figure 3
The diagram is arranged in a vertical flow with a timeline on the left and a series of steps in boxes. The left-hand side is labeled with a vertical timeline that includes four main stages: Identification, Screening, Eligibility, and Included. The flow of boxes begins with Identification: This stage includes a box labeled “Records identified in Scopus database” with Lowercase n equals 124. An arrow points down to the Screening stage, which includes a series of boxes: “Records screened” with Lowercase n equals 124. An arrow points to the right to a box labeled “Records excluded.” This box details the reasons for exclusion: (No author) equals 10, (Duplicates) equals 27, and (non-relevant articles) equals 30. An arrow from the “Records screened” box points down to a box labeled “Record after screening” with Lowercase n equals 57. An arrow points down to the “Eligibility” stage: This stage includes a box labeled “Full text articles assessed for eligibility” with Uppercase N equals 57. An arrow points to the right to a box labeled “Full text articles excluded as exceeding floor level criteria equals 8.” An arrow points down to the final “Included” stage: This stage includes a box labeled “Total papers included” with Uppercase N equals 49.PRISMA protocol for bibliometric search and screening.
