Why This Matters For Medical Reading
Clinical choices and patient safety lean on reliable studies. A quick, repeatable check helps you tell screened research from unchecked posts and preprints.
How To Check If A Medical Article Is Peer Reviewed: Step-By-Step
Step 1: Identify The Journal And Article Type
Start with the landing page or PDF. Note the journal name, article type, and DOI. Editorials, letters, and news pieces rarely undergo full external review, while original research and systematic reviews usually do.
Step 2: Look For Proof On The Article Page
Peer-reviewed medical papers often show workflow stamps near the first page: “received,” “revised,” and “accepted” dates. Many also add a “peer review statement,” a handling editor, or a badge for transparent review. If the journal runs open review, look for linked reports.
Step 3: Read The Journal’s Peer Review Policy
Open the journal site’s “About,” “Instructions for Authors,” or “Editorial Policies.” You should see the type of review used, how many reviewers, and handling of editor-authored work. Cross-check ethics pages for trial registration and data rules. Many journals cite the ICMJE recommendations.
Peer Review Checks: What To Do And Where
| Check | Where To Verify | What To Look For |
|---|---|---|
| Workflow dates | Article PDF or HTML | “Received,” “revised,” “accepted” lines near the abstract or footer |
| Peer review statement | Article page | A line that states the paper was externally reviewed; links to reports if open review |
| Policy details | Journal “About” or “For authors” | Single-anonymous, double-anonymous, or open review; number of reviewers; handling editor rules |
| COPE membership | Journal ethics page | Logo or link to the Committee on Publication Ethics; clear misconduct process |
| ICMJE alignment | Journal instructions | Reference to authorship, conflicts, data sharing, and trial registration |
| Indexing status | NLM Catalog | “Currently indexed for MEDLINE,” PubMed linking, title history |
| Editorial board | Journal masthead | Named academics with affiliations; low endogeny; conflict disclosures |
| Submission system | Journal site | Standard platforms (Editorial Manager, ScholarOne) or clear in-house workflow |
| Article type | Article header | Original research, randomized trial, review, meta-analysis, brief report |
| Predatory signals | Journal homepage | Promises of “guaranteed acceptance,” fake metrics, fees with no service detail |
Step 4: Use Trusted Medical Gateways
Search the NLM Catalog to locate the journal record. If you see “Currently indexed for MEDLINE,” the title has passed a curated review of scientific and editorial quality. For open-access journals, a listing in DOAJ signals that the journal declares peer review and meets transparency checks.
Step 5: Confirm Peer Review Is Stated, Not Implied
PubMed as a platform does not offer a “peer-review only” limiter (NLM explains why here). That means you still need the journal policy. When in doubt, email the editorial office and ask for a link to the policy page and the model used for your article type.
Step 6: Record Your Evidence
Save the policy link and a screen capture of the article’s dates or review note. This helps with audits, appraisals, and teaching.

What “Peer Reviewed” Means In Medical Journals
Common Models And What They Mean
Medical titles most often use single-anonymous review. Some use double-anonymous to limit identity signals. A growing group posts open reports. The model alone does not prove quality; transparency around the process helps you judge real practice.
Why MEDLINE Status Helps
MEDLINE indexing brings subject headings, curated selection, and consistent metadata. The process weighs scope, editorial policies, and research quality. It does not stamp every item as peer reviewed, so still read the article page.
Using PubMed, MEDLINE, And Editorial Policies Together
Start With The Article
Open the abstract page and switch to the publisher site. Check the PDF first page for dates. Then read the “About” page to confirm the policy and model for your article type.
Then Check The Journal Record
Search the NLM Catalog by journal title or ISSN. Note current indexing status and any title changes that might explain gaps. For open-access titles, confirm a DOAJ entry and a clear peer review description on the journal site.
Finish With A Policy Screenshot
Store a copy of the policy and any linked reviewer reports locally. Shared folders make team checks faster.
Peer Review Models: What You’ll See And How To Read Them
Journal sites label models in different ways. Use the notes below when you read a policy page or an open-review package.
| Model | How It Works | What It Means For You |
|---|---|---|
| Single-anonymous | Reviewers see author names; authors do not see reviewer names | Common in medicine; watch for bias safeguards and editor oversight |
| Double-anonymous | Neither side sees names during review | Reduces identity cues; check how de-identification is handled |
| Open review | Names and reports may be public | You can read the reports; good for teaching and appraisal |
| Transparent review | Anonymous reports posted with the paper | See decision letters and responses without names |
| Registered reports | Methods and analysis plan reviewed before data collection | Strong guard against outcome switching in trials |
| Post-publication review | Public comments after release | Useful for ongoing critique; still seek pre-publication review for clinical use |
Red Flags That Waste Time
Marketing Language Instead Of Policy
If the “About” page sells reach and speed but skips reviewer selection, criteria, and ethics, be cautious. Real policies list steps, not slogans.
Unclear Fees Or Fake Metrics
Look for honest APC details, waivers, and what the fee includes. Be wary of fake impact claims or badges that do not link to a real source.
Mass Editor Authorship
Scan recent issues. If a large slice is written by editors or the board, peer review may be weak. DOAJ calls this endogeny and flags it during checks.
Build A Fast Routine You Can Reuse
The Two-Minute Triage
1) Article page: dates and peer review note. 2) Journal policy page: model and reviewer count. 3) NLM Catalog or DOAJ record: indexing and transparency. Save links in your notes app.
Deeper Verification For High-stakes Use
Skim the editorial board for real affiliations. Search the site for peer review examples. Read any posted reports. Keep notes on past checks so the next one takes seconds.
Frequently Missed Details That Matter
Article Type Vs. Policy
Some journals use external review for research but not for letters or viewpoints. The policy should spell this out. Match the policy to the exact article type in front of you.
Editor-Authored Papers
Legit journals describe how they handle submissions by editors and board members: independent handling editors, extra reviewers, or external oversight. Check for this line in the policy.
Clinical Trials And Data Standards
Strong medical journals require trial registration, CONSORT flow diagrams, and data sharing statements. These signals pair well with a clear review policy.
Tools That Make Checking Faster
NLM Catalog Tips
Search by ISSN to avoid title variants. Use the “Currently indexed for MEDLINE” flag to gauge curation. Then click through to the publisher page for the policy.
Think. Check. Submit.
Keep the one-page checklist pinned to your bookmarks bar. It prompts you to verify editorial board, contact details, indexing claims, and peer review steps.
Library Directories
If your library subscribes to Ulrichsweb, search the journal and look for the “refereed” tag. That tag maps to peer-review status.
Edge Cases: Preprints, Conference Supplements, And Revisions
Preprints
Medical preprints live on servers like medRxiv. They are not peer reviewed. Many journals permit posting revised versions after peer review; the article page should link the versions.
Conference Supplements
Supplements may carry lighter screening than regular issues. The journal policy should explain how abstracts and proceedings are handled.
Accepted Manuscripts And Versions
Publishers may host accepted author manuscripts before copyedit. These still show acceptance dates and link to the record of peer review if the journal posts it.
How To Read A Peer Review Policy Like A Pro
What A Solid Policy Usually States
Look for the review model, typical number of reviewers, scope of checks (methods, statistics, ethics), and timelines from submission to first decision. Strong policies describe how conflicts are managed, how appeals work, and how complaints are handled. Many medical titles point to the ICMJE rules on authorship, conflicts, data, and trial registration; a link to those recommendations is a good sign.
What Vague Policies Tend To Omit
Watch for pages that talk about “quality review” without naming external reviewers, or that only mention an editor screening. If you see a promise of instant decisions or acceptance, stop and verify with independent sources before you cite or submit.
Open Review Artifacts Worth Saving
Some journals publish reviewer reports and decision letters alongside the paper. Save these PDFs. They help with teaching and audits. You can quote the report’s main concerns when you brief a team on risk or study limits.
Step-By-Step Walkthrough In PubMed And The NLM Catalog
From PubMed To The Publisher
Search for the article in PubMed. Open the abstract page, then click the publisher icon to reach the full text. Many abstract pages also show a “journal information” link that leads to details about the title and its history. Use that to spot title changes or supplements.
From PubMed To The Journal Record
Open the journal’s record in the NLM Catalog. Copy the ISSN and confirm the current title. Read the “currently indexed for MEDLINE” line and the “linking ISSN” field. This helps you match older issues to the same family when a title changed names over time.
When The Paper Is Open Access
Many open-access titles post clear peer review pages and, in some cases, the review history. Others rely on email claims. Use the same routine: article dates, policy page, and indexing record. If the site claims a DOAJ listing, you can check that quickly on the DOAJ site.
Quality Signals Beyond Peer Review
Reporting Standards
For trials, look for a registration ID, a CONSORT diagram, and a protocol link. For systematic reviews, look for a registered plan and PRISMA flow. These are not review by themselves, yet they pair well with solid policies and help you judge the work.
Data And Ethics
Find data sharing statements, IRB approval lines, and patient consent language where relevant. Medical journals that ask for these items tend to run tighter editorial checks.
Practical Templates You Can Reuse
One-Page Audit Note
Create a short note you can paste into appraisals. Bullets: journal name and ISSN, model quoted from the policy, article dates, MEDLINE status, and any posted reports. Attach screenshots.
Team Training Sprint
Pick one article, split the team, and time the check: five minutes on the article page, five on the policy, five on the journal record. Share the proof and rotate roles.
When You Need More Help
Ask Editors The Right Questions
If a policy is unclear, send a short email. Ask which model applies to your article type, how many reviewers are assigned, and how editor-authored work is handled. A prompt, specific reply builds trust. Save the email in your evidence folder.
Lean On Library Pros
Hospital and university librarians run these checks daily. They can verify indexing, policy history, and journal title changes, and many give short training sessions on PubMed features and catalog searches.
Put It All Together
With practice, you can confirm peer review in minutes. Start at the article page, read the policy, and verify the journal record. Save proof so your team can reuse your work.
