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 For each one we check whether it exists and, where the source flags it, whether it has been retracted.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.
