Figure 2
The flowchart illustrates the research article identification, screening, and eligibility process using rounded rectangular text boxes connected by arrows. At the top, two separate boxes appear side by side. The left box reads “Research articles searched through database search (n equals 765)”, and the right box reads “Research articles searched through Google Scholar (n equals 658)”. Downward arrows from both boxes lead to a single box reading “Research articles after removing duplicates (n equals 687)”. A downward arrow leads to a box labeled “Research articles for screening (n equals 687)”. A downward arrow from the screening box leads to another box labeled “Research articles retained for eligibility (n equals 43)”. A right-pointing arrow from a box labeled “Articles excluded related to other disciplined except Performance (n equals 644)” leads to the downward arrow from Research articles for screening (n equals 687). A final downward arrow from the eligibility box leads to the bottom box labeled “Research articles for screening (n equals 34) (observation equals 11333)”. A right-pointing arrow from a box labeled “Articles excluded (n equals 9): Exclusion includes qualitative research, no data for direct effect, same data, et cetra”, leads to the downward arrow from Research articles retained for eligibility (n equals 43). A final downward arrow from the eligibility box leads to the bottom box labeled “Research articles for screening (n equals 34) (observation equals 11333)”.PRISMA flow diagram.
