Retraction Checker for Medical Citations

Paste up to 5 PubMed IDs (PMID:12345678), DOIs, or ClinicalTrials.gov numbers (NCT01234567). For each one we check whether it exists and, where the source flags it, whether it has been retracted — the same live PubMed, Crossref, and ClinicalTrials.gov sources our full medical product checks against, with no LLM involved in this verdict. No account required. Small daily limit (3 checks/day), separate from any account allowance on the full product.

Not covered: bare journal citations with no PMID/DOI/NCT identifier — those are recognized and counted but flagged outside coverage rather than fuzzy-matched, the same honest limit documented at /methodology.

Citation Safe is not a medical or legal advice service. Existence and retraction checks are performed against PubMed (NCBI E-utilities), Crossref, and ClinicalTrials.gov only — no other source is queried by this tool. See methodology for exact verdict semantics.
