Understanding the clash between PRISMA and the journal’s combined methods‑results layout
You're in the thick of drafting your capstone, and your advisor has reminded you that a systematic review should follow the classic PRISMA structure: separate Introduction, Methods, Results, Discussion, and a dedicated flow diagram. At the same time, the journal you’re targeting publishes systematic reviews in a single “Methods & Results” section, merging the two for brevity. The tension feels like a tug‑of‑war between academic rigor and editorial practicality.
The core difficulty is not just about moving a paragraph here or there; it’s about preserving the transparency that PRISMA guarantees while respecting the journal’s stylistic constraints. If you simply copy‑paste the PRISMA headings into a format the journal rejects, the manuscript will be sent back for “non‑conformity.” If you strip away too much detail, reviewers may question whether you actually conducted a systematic search.
Think of the problem as a two‑part puzzle: (1) identify which PRISMA elements are non‑negotiable for credibility, and (2) translate those elements into the journal’s combined layout without losing the logical flow. Below is a step‑by‑step checklist that keeps the essential pieces intact while allowing you to comply with the journal’s style guide.
“I was terrified that merging the sections would hide my search strategy, but after mapping each PRISMA item to a paragraph in the combined section, my reviewers praised the clarity.” – a senior who submitted a systematic review to a medical education journal.
Actionable takeaway: Pinpoint the must‑have PRISMA components first; they will guide every formatting decision you make.
Mapping PRISMA requirements onto a single “Methods & Results” heading
Start by listing the 27 PRISMA items (or the newer 2020 checklist if you’re using it). Highlight the ones that directly affect reproducibility: protocol registration, eligibility criteria, information sources, search strategy, selection process, data extraction, risk of bias assessment, and synthesis methods. Those items must appear somewhere in your manuscript, even if the journal lumps them together.
Next, draft a hybrid outline that respects the journal’s heading hierarchy but still signals each PRISMA element. For example:
- Brief background (serves as a condensed Introduction).
- Methods & Results – start with a paragraph titled “Protocol and Eligibility Criteria,” then flow into “Search Strategy and Study Selection,” followed by “Data Extraction and Quality Assessment,” and finally “Synthesis of Findings.” Each sub‑paragraph can end with a concise result statement (e.g., “The search yielded 1,842 records, of which 42 met inclusion criteria”).
- Discussion – keep separate as required.
- Conclusion and Implications.
Notice how the search results are embedded directly after the description of the search strategy. This satisfies the journal’s combined format while still reporting the numbers that PRISMA expects.
When you write the “Methods & Results” section, use transition phrases that make the shift from description to outcome explicit. Phrases like “Based on the above criteria, we identified…” or “Applying the extraction protocol described earlier, we found…” act as signposts for readers and reviewers.
One common mistake is to place all the numbers in a table at the very end of the manuscript, hoping the narrative will cover the rest. Journals that require a merged section often want the numbers interwoven with the narrative, not isolated. Keep the flow tight: describe the method, then immediately report the key figure.
“I initially put my PRISMA flow diagram in the appendix, but the editor asked for it in the main text. By inserting a brief ‘Study selection’ paragraph with the diagram, I kept the narrative seamless.” – a graduate student in psychology.
Actionable takeaway: Write a single “Methods & Results” heading that contains mini‑subsections, each pairing a PRISMA item with its corresponding outcome.
Adapting tables and figures without sacrificing clarity
You've already shuffled your tables to fit the journal’s style, but the question remains: how far can you go? The answer hinges on two principles: (a) preserve the information hierarchy, and (b) maintain traceability to the PRISMA checklist.
Begin by auditing each table. Does it answer a specific PRISMA item? For instance, a table summarizing study characteristics directly supports the “Characteristics of Included Studies” item. If a table merely repeats information already in the narrative, consider merging it into a concise paragraph or a supplemental file.
Here’s a quick decision framework you can copy into a spreadsheet:
| Table purpose | PRISMA link | Keep, modify, or move? |
|---|---|---|
| Search strategy details | Item 7 (Search) | Keep as a boxed text within the methods paragraph. |
| Risk of bias scores | Item 12 (Risk of bias assessment) | Modify: turn into a compact figure with a legend. |
| Outcome effect sizes | Item 14 (Synthesis of results) | Keep: embed in the results narrative with a summary table. |
| Supplementary coding scheme | Item 10 (Data items) | Move to online supplement. |
When you embed a table inside the combined section, precede it with a brief lead‑in sentence that references the relevant PRISMA item. Example: “Table 1 presents the data extraction fields outlined in Item 10 of the PRISMA checklist.” This explicit link reassures reviewers that you haven’t omitted any required detail.
A frequent pitfall is to over‑compress tables to fit page limits, resulting in unreadable fonts or ambiguous column headings. If the journal imposes strict word or page counts, negotiate a supplemental file rather than sacrificing legibility. Most reputable journals accept online supplements, and they are considered part of the official record.
“My advisor warned me against shrinking the risk‑of‑bias table to a single column. I kept the original layout, placed it after the synthesis paragraph, and the reviewers praised the transparency.” – a senior in public health.
Actionable takeaway: Align each table with a PRISMA item, then decide to keep, modify, or move it based on that alignment.
Communicating deviations to your advisor and the journal editor
Even after you’ve restructured the manuscript, you’ll likely need to explain why certain PRISMA headings are absent or merged. The safest route is a brief cover letter or a “Methods & Results” footnote that outlines the correspondence between the journal’s format and the PRISMA checklist.
Draft a three‑sentence note for the editor:
- State that the manuscript follows the journal’s combined “Methods & Results” format.
- List the PRISMA items that are still fully reported, referencing the specific sections or tables where they appear.
- Offer to provide a supplemental PRISMA flow diagram if the editor wishes to see the traditional layout.
When you discuss the changes with your advisor, bring a side‑by‑side comparison: on the left, the classic PRISMA outline; on the right, the journal’s combined outline with annotations showing where each PRISMA element lives. This visual aid often diffuses tension because it demonstrates that you haven’t “cut corners”—you’ve simply repackaged the same information.
Students sometimes assume that the advisor will automatically accept any format that satisfies the journal. In reality, advisors may be protecting you from future credibility issues. By proactively showing the mapping, you respect both parties’ expectations.
“My advisor was skeptical until I showed a table that matched each PRISMA item to a paragraph in the combined section. He signed off, and the editor later thanked me for the clear mapping.” – a doctoral candidate in nursing.
Actionable takeaway: Prepare a concise mapping document for both advisor and editor to demonstrate that no PRISMA requirement has been omitted.
Final checklist before submission and the first concrete step you can take now
Before you hit “Submit,” run through this short but comprehensive checklist. It captures the most common slip‑ups that can cause a manuscript to be returned for formatting issues.
- Verify that every mandatory PRISMA item appears at least once in the manuscript.
- Confirm that each PRISMA‑linked table or figure is placed immediately after the paragraph that introduces it.
- Ensure the combined “Methods & Results” heading contains clear sub‑headings or transition sentences for each PRISMA component.
- Check that the flow diagram (if required) is embedded within the main text, not hidden in an appendix.
- Write a one‑paragraph mapping note for the editor and a side‑by‑side outline for your advisor.
- Run a final word‑count on each section: aim for 250‑400 words per
block to stay within the article’s length guidelines.
- Proofread for consistency of terminology (e.g., “eligible studies” vs. “included studies”).
If any item feels shaky, revisit the relevant PRISMA checklist entry and add a sentence or two. The goal is not to inflate the manuscript but to make every methodological decision traceable.
Now, the immediate action you can take: open your current draft, locate the first PRISMA item (usually the protocol registration), and write a one‑sentence bridge that connects it to the next item (search strategy). For example: “Our protocol, registered in PROSPERO (ID XXXX), guided a systematic search of PubMed, Scopus, and Web of Science, which identified 1,842 records.” This single sentence simultaneously satisfies two PRISMA items and demonstrates the merged style you need.
Actionable takeaway: Insert a bridging sentence that pairs a PRISMA requirement with its outcome; repeat this pattern until the entire “Methods & Results” section reads as a cohesive narrative.
