The PRISMA flow diagram titled “Identification of studies via databases and registers” and shows three section headings arranged vertically on the left side: “Identification,” “Screening,” and “Included.” The flowchart is divided into two columns. The left column contains five text boxes, which are labeled as follows: Text box 1: Records identified from asterisk: Databases (n equals 3.365). Text box 2: Records screened (n equals 2.325). Text box 3: Reports sought for retrieval (n equals 433). Text box 4: Reports assessed for eligibility (n equals 405). Text box 5: Studies included in review (n equals 72). The right column contains four text boxes, which are labeled as follows: Text box 6: Duplicate records removed through EndNote (n equals 1.039). Text box 7: Records excluded double asterisk (n equals 1.893). Text box 8: Reports not retrieved triple asterisk (n equals 28). Text box 9: Reports excluded: Out of Scope (n equals 37), Wrong Population (n equals 9), Conceptual Papers (n equals 113), Measuring Perceived Employability (n equals 146), Outside Curriculum (n equals 10), Comparative Studies (n equals 18). The text boxes 1 and 6 are placed under the heading “Identification,” the text boxes 2, 3, 4, 7, 8, and 9 are placed under the heading “Screening,” and the text box 5 is placed under the heading “Included.” Text box 1 is connected to text box 2 with a downward arrow. Text box 2 is connected to text box 3 with a downward arrow. Text box 3 is connected to text box 4 with a downward arrow. Text box 4 is connected to text box 5 with a downward arrow. Text box 1 is connected to text box 6 with a rightward arrow. Text box 2 is connected to text box 7 with a rightward arrow. Text box 3 is connected to text box 8 with a rightward arrow. Text box 4 is connected to text box 9 with a rightward arrow.Study selection process following PRISMA 2020 guidelines (Page et al., 2021a). Note: *ERIC (n = 540); Web of Science (n = 1.274) and Scopus (n = 1.551). **Papers screened for relevance by title and abstract. ***Not retrievable or later identified duplicates.
