PRISMA Flow Diagram Generator
Type the counts from each stage of your systematic review and this PRISMA flow diagram generator draws the PRISMA 2020 chart for you: identification, screening and included boxes, arrows, exclusion reasons and totals. It checks that the numbers add up, then lets you edit every box and export a clean PNG, SVG or PowerPoint file.
Free: PRISMA diagrams never cost credits. A free account is needed to edit boxes and download files.
What Is a PRISMA Flow Diagram Generator?
A PRISMA flow diagram shows how a systematic review went from thousands of search results to the handful of studies it analyses. Drawing one by hand means lining up boxes, arrows and numbers in Word or PowerPoint and redoing the arithmetic every time a count changes. A PRISMA flow diagram generator takes the counts once and builds the standard layout, so the figure always matches the numbers in your methods section.
What a PRISMA Flow Diagram Records
The chart follows records through three phases. Identification lists where records came from and how many were removed before screening as duplicates or for other reasons. Screening shows records screened and excluded, reports sought and not retrieved, and reports assessed for eligibility with the reasons for exclusion. Included gives the final number of studies and of reports describing them.
PRISMA 2020 Flow Diagram Generator Layout
PRISMA 2020 has four official templates: new or updated reviews, each searching databases and registers only, or other methods as well, such as websites, organisations and citation searching. Switch on an updated review or other methods in the form and the PRISMA 2020 flow diagram generator adds the previous-studies column or the second identification column with its own arrows.
PRISMA Flow Diagram Template vs. a Generator
A PRISMA flow diagram template is a fixed Word file: you type each number into a text box and resize boxes when the text wraps. Here the boxes size themselves to their text, empty counts stay as (n = ) placeholders, and the tool fills in counts that follow from earlier ones, so an updated search never leaves a stale total behind.
Why Use Our PRISMA Flow Diagram Generator?
Reviewers and editors read the flow chart first to judge how rigorous the search was. Our PRISMA flow diagram generator focuses on the two things that most often go wrong: numbers that do not reconcile, and figures that cannot be changed when the reviewers ask for one more search.
Free PRISMA Flow Diagram Generator Online
Everything runs in the browser and the preview updates as you type, with no software to install. Generating and editing PRISMA charts never uses credits, so this free PRISMA flow diagram generator online stays free for every revision of your review. A free account keeps your diagrams so you can come back after peer review.
Every Box Is Editable Vector
The result is not a picture of a diagram. Each box, label and arrow is a separate object you can move, recolour or retype in the editor, and box text such as "Reason 1" becomes your real exclusion reason. Built-in checks flag a screened count that does not equal identified minus removed before a reviewer spots it.
Ready for Word, Slides and Journals
Download PNG or JPG at 300 or 600 dpi for submission, SVG for a sharp vector figure, or PPTX with editable text boxes for your defence slides. The same account also draws illustrations, mechanisms and other figures for the rest of the paper.
Make other scientific figuresHow to Create a PRISMA Flow Diagram in 3 Steps
To create a PRISMA flow diagram you only need the counts from your search log and screening software, such as Covidence, Rayyan or a spreadsheet. It takes about two minutes.
Enter Your Screening Counts
Add records found in databases and registers, duplicates and other removals, then records screened and excluded, reports sought, not retrieved and assessed, and each exclusion reason with its count. Tick "updated review" or "other sources" if they apply.
Check the Generated Diagram
Watch the PRISMA 2020 chart update beside the form. Press "Fill in derived counts" to complete totals that follow from earlier boxes, and fix any count flagged in yellow until every stage adds up.
Edit and Export
Open the diagram in the editor to change wording, colours or fonts, add a title or footnote, then download PNG, SVG or PPTX and insert it as Figure 1 of your review.
