Retracted papers do not quietly disappear from science. They keep getting cited, show up in reviews and meta-analyses, and can shape guidance years after they are withdrawn. This guide explains why that happens and how simple checks and tools can help you avoid using unreliable work.
What a retracted paper is and why retraction happens
A retraction is a public notice that a paper should no longer be treated as reliable.
It signals serious problems such as major error, made‑up data, plagiarism, unethical methods, or duplicate publication. Good practice is that the retraction notice links to the paper and clearly explains who is retracting it and why, as COPE and major indexing services recommend.
Why retracted papers continue to be cited
You might expect citations to stop once a paper is retracted.
In fact, many retracted papers keep getting cited, and most of those new citations do not mention the retraction at all. Studies across fields, including dentistry, biomedicine, and engineering, show that more than half of retracted items continue to attract citations. Only a small share of citing papers warn readers that the study has been withdrawn.
Three simple reasons explain most of this:
- Retraction notices can be slow to appear and slow to spread across databases.
- Old PDFs and saved copies often show no clear warning.
- Many authors reuse old reference lists or trust their reference manager without checking the current status of key papers.
How ongoing citations to retracted work harm research quality
Citing retracted work is not a minor slip. It can change what we think the evidence shows and affect real‑world decisions.
Bias in reviews
When systematic reviews and meta-analyses include retracted trials, the combined effect size and statistical significance can shift in important ways.
In some cases, clinical guidelines built on these reviews change once the retracted trials are removed. One flawed study can therefore influence patient care and policy long after it should have been discounted.
Spreading wrong results
If later studies or reviews treat a retracted paper as sound, new hypotheses, interventions, and even products may rest on bad data. This wastes time and funding and can expose patients or users to real risk.

Skewed scores and reputations
Citations to retracted work still count in many metrics, including journal impact factors and author h‑indices, unless databases mark and correct them. Some services are improving how they handle this, but coverage and consistency are still uneven.

Why detection fails: metadata, versions, and human habits
In practice, missed retractions usually come down to three simple problems.
Out‑of‑date records
Different systems do not always update at the same time. A publisher may add “retracted” to the online article, but that change can take time to show up in Crossref, PubMed, and other indexes.
Old copies in circulation
Many people work from downloaded PDFs, printouts, or files shared by colleagues. These copies rarely show any retraction banner or watermark, so the reader has no clear signal that the article is no longer valid.
Human habits
Authors and reviewers often trust memory or old reference‑manager libraries.
Without a deliberate check before submission, it is easy for a retracted paper to slip into a reference list, even when databases do mark it as retracted.
Because of these issues, you need both simple tools and simple habits to catch problem papers.
How you can check citations for retraction (quick checklist)
You do not have to audit every item in your reference list. Focus on the papers that really hold up your argument: key trials, highly cited reviews, and any “first” study in an area. For those, use this quick checklist before you submit.
- Open the DOI landing page and check the publisher’s site for a clear retraction or correction notice.
- Use Crossref or Crossmark to see whether the DOI has any status updates.
Crossmark - Search the Retraction Watch Database by title or DOI to see if the article appears there.
- For biomedical papers, look up the article in PubMed and check for “retracted publication” labels and linked notices.

These steps take only a few minutes per important paper but can prevent major rework and embarrassing corrections later.
Before / after example (how to correct a citation in your manuscript)
When you find out that a paper you have cited has been retracted, you may not always need to delete it, but you must not present its findings as reliable support.
Before:
“Smith et al. report a 40% reduction in outcome X (Smith et al., 2010).”
After discovering retraction:
“Smith et al. reported a 40% reduction in outcome X, but this study was later retracted for data fabrication and should not be used as supporting evidence (Smith et al., 2010; retracted). Consider citing independent replications that remain valid.”
If the retracted paper is central to your main claim, you should explain the retraction clearly and then revise the argument or remove that claim altogether.
How tools and workflows reduce the risk
The more references you manage, the harder it is to check everything by hand.
This is where tools and simple workflows help. Crossmark and Crossref let you query status information directly. Retraction Watch provides a detailed database of retractions across fields.
PubMed links original papers to their retraction notices and flags “retracted publication” in the record. Some reference managers and manuscript‑checking services now pull in this information and flag suspicious items while you write.
How Trinka’s Citation Checker can help (practical fit)
Trinka’s Citation Checker is one example of such a tool. It can scan your reference list to identify possible retracted citations, check DOIs against Crossref, and highlight very old or unverified references that might weaken your work.
You can then manually review any flagged items: open the publisher record, confirm the retraction notice, or replace the study with better evidence. Trinka’s Citation Checker works best as an early warning system, not a final authority.
Best practices for authors, reviewers, and editors
A few small habits can greatly reduce the chance that you will cite retracted work.
- Make a quick retraction check part of your process for any key citation.
- If you remove a retracted paper during revision, mention this briefly in your cover letter or response to reviewers.
- When in doubt, check more than one source, for example, compare Crossref, Retraction Watch, and PubMed when records disagree.
- For reviews and meta-analyses, state clearly how you searched for and handled retracted studies.
Practical next steps you can use now
Retracted papers still cause trouble because people keep citing them and they stay in databases for years. Reviews and guidelines may still treat them as solid evidence even after they are withdrawn.
Before you submit your next paper or review, pick your most important citations and give them a quick status check. Open the DOI page, look for a retraction or correction, and confirm the record in Crossref or Crossmark. For clinical or biomedical work, also check PubMed and search the Retraction Watch Database when a study looks especially “too good to be true.”
Tools such as Trinka’s Citation Checker can help by flagging papers that might be retracted or otherwise risky so that you can double‑check them by hand.
This takes a little extra time but protects your work and shows that you take research integrity seriously.
