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,” “SELECTION,” “ELIGIBILITY,” and “INCLUSION.” In the “IDENTIFICATION” stage, a text box reads “Records identified in databases (n equals 1925).” A line extends downward from this text box and leads to the “SELECTION” stage with a text box labeled “Records after deleting duplicates (n equals 843).” A line extends downward and connects to another text box in the same stage labeled “Records reviewed (n equals 542).” A line extends downward from “Records reviewed (n equals 542)” and connects to the “ELIGIBILITY” stage with a text box labeled “Records evaluated for full text reading (n equals 79).” A line extends right to a text box labeled “Records deleted due to exclusion criteria (n equals 463)” in the same stage. A final line extends downward from “Records evaluated for full text reading (n equals 79)” to the “INCLUSION” stage with a text box reading “Registers included (n equals 60).” A line extends right to a text box that reads “Rejected after reading the methodology (n equals 19)” in the same stage.PRISMA data collection process.
