A PRISMA flow diagram records how citations move through identification, deduplication, screening, eligibility assessment, and inclusion. Counts must reconcile across stages and exclusions need defensible reasons; the diagram documents selection flow but does not assess the quality of the review itself.
PRISMA Flow Diagram Builder applies this concept to its defined inputs and workflow. It organizes screening counts for reporting support.
The helper structures key-value screening counts and returns PRISMA count table, flow visual, and screening summary so decisions and omissions can be reviewed explicitly. Input structure, labels, missing values, and selected options must match the intended workflow. It supports preparation and independent checking rather than replacing the governing software, standard, evidence, or professional review. The visual is a planning summary, not an official PRISMA template.
