How do I cite missing exclusion criteria in a PRISMA flowchart?
When a PRISMA flow diagram does not display the small box that lists excluded studies and the reasons for exclusion, the correct APA 7 approach is to treat the omission as a “missing element” and provide a narrative note in the text of your methods section. Write a sentence such as: “The original PRISMA diagram (Author, Year) omitted the detailed exclusion reasons; these are summarized in Table 2.” Then create a separate table that reproduces the missing information or, if you cannot recover it, state that the original source did not disclose the reasons. In the figure caption you add a brief explanation: Note: the exclusion‑criteria box is not shown in the source diagram. This satisfies both the PRISMA requirement for transparency and the APA 7 rule that every figure must be fully described in the caption or accompanying text.
Do not try to guess the missing text; instead acknowledge the gap. If you have access to the study’s supplementary files, pull the exclusion list from there and cite the supplement. The citation format follows the standard author‑date style, and the figure caption must include the word “Figure” followed by an Arabic numeral, a concise title, and the note about the omission.
Actionable takeaway: add a caption that explicitly mentions the missing box and reference the source with a normal APA in‑text citation.
Why might the exclusion text be invisible to a screen reader?
Many PRISMA templates are built in PowerPoint or Word using tiny text boxes that sit on top of the main flow arrows. When the diagram is exported as a PDF, those boxes often become separate layers that lack proper alt‑text. Screen‑reader software therefore skips them, leaving you with a silent gap. The problem is not a formatting trick by the author; it is a common accessibility oversight.
“My screen reader kept jumping from ‘Records identified’ straight to ‘Full‑text articles screened.’ I couldn’t tell whether the exclusion reasons were omitted on purpose or just hidden.” – a graduate student with a visual processing disability
To verify whether the original author truly left the box empty, open the source file (if your advisor can share it) and look for a layer named “Exclusions.” If the layer exists but the text is set to a font size smaller than 8 pt, increase it to at least 10 pt and add alt‑text that reads, for example, “10 studies excluded for not meeting inclusion criteria.” When you re‑export the diagram, the screen reader will announce the content.
Actionable takeaway: check the source file for hidden layers and add alt‑text before you embed the figure in your manuscript.
How can I avoid integrity concerns when noting a gap?
Academic integrity policies treat the intentional omission of required information as a form of misrepresentation. By clearly labeling the missing exclusion box, you demonstrate that you are not trying to hide a flaw. APA 7 advises that any deviation from the original figure must be disclosed in a caption or footnote. Use language that signals transparency, such as “The original diagram did not provide detailed exclusion reasons; the author’s omission is noted here.”
Do not fabricate reasons or copy them from another study. If you have no way to retrieve the original list, state that the information was not reported. This approach satisfies plagiarism detectors because you are not presenting another author’s text as your own, and it satisfies reviewers who look for full methodological reporting.
Actionable takeaway: always accompany a note about missing content with a citation to the original source and a brief explanation of why the information is unavailable.
Which checklist items should I double‑check before I hit submit?
Before the deadline, run through a concise verification list. The list aligns with the PRISMA 2020 checklist and APA 7 figure standards. Each item is phrased as a concrete action you can perform in five minutes or less.
| Checklist item | What to verify | Common slip | Fix |
|---|---|---|---|
| Caption completeness | Figure number, title, and note about missing box | Caption ends without a note | Add “Note: exclusion‑criteria box omitted in source.” |
| Alt‑text presence | Screen‑reader description for every layer | Alt‑text missing for hidden box | Insert concise alt‑text in the source file. |
| In‑text citation | Author, year, and figure reference in methods | Only a parenthetical citation appears | Write “see Figure 3 (Author, Year).” |
| Table of exclusions | Separate table reproducing missing reasons | Table omitted or unlabeled | Create Table 2 with clear column headings. |
Run this checklist after you finish the caption and before you export the final PDF. If any item flags red, pause and correct it; the time saved later is worth the few extra minutes now.
Actionable takeaway: use the table as a nightly audit to guarantee that every PRISMA requirement is visibly satisfied.
What does a successful PRISMA appendix look like at the end of the semester?
By the final week, your systematic‑review appendix should read like a transparent roadmap. The flow diagram displays all four standard boxes—identification, screening, eligibility, and inclusion—plus a clearly labeled note for the exclusion‑criteria box. The caption beneath the diagram includes the author‑date citation, the word “Note,” and the exact phrasing required by APA 7. A supplemental table lists each excluded study with its reason, even if the original source omitted that detail.
Reviewers will scan for three signs of completeness: (1) a caption that explains any deviation, (2) alt‑text that lets assistive technology convey every part of the figure, and (3) a cross‑reference in the methods that tells the reader where to find the full exclusion list. When those three are present, the appendix meets both PRISMA transparency standards and APA 7 formatting rules.
Actionable takeaway: after you have checked the list, view the PDF with a screen reader yourself; if the reader announces the exclusion reasons, you have achieved a fully accessible and correctly cited PRISMA flowchart.
