About the PRISMA 2020 flow diagram
The PRISMA flow diagram documents how you moved from all the records your search returned to the final set of studies in your review. Reviewers and journals expect it for any systematic literature review, and it makes your screening reproducible. This maker follows the PRISMA 2020 structure: identification, screening, and included.
Tip: the numbers must reconcile - records screened minus excluded should flow into reports sought, and so on. If the boxes don't add up, reviewers will notice. For the full method - search strings, eligibility criteria, and writing it up - see the SLR & paper-writing workshop.
