Probe: `GET https://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?db=pubmed&id=9500320&retmode=xml`
(E-utilities, keyless; PMID 9500320 is the same Wakefield 1998 Lancet paper as S1/S2).

Observed response (HTTP 200, PubMed XML):
- `<PublicationTypeList>` includes `<PublicationType UI="D016441">Retracted
  Publication</PublicationType>` alongside `Journal Article` and `Research Support`.
- `<CommentsCorrectionsList>` carries 26 entries total for this one PMID, mostly
  `RefType="CommentIn"` (contemporaneous letters), but critically:
  - `RefType="RetractionIn"`, PMID 15016483, dated 2004-03-06 — a **partial**
    retraction (of the interpretation, by 10 of 13 co-authors, pre-dating the full one).
  - `RefType="RetractionIn"`, PMID 20137807, dated 2010-02-06 — the **full**
    retraction (same DOI as S2 in this lane).
  - `RefType="ExpressionOfConcernIn"`, PMID 21971344, dated 2011-11, in *Eur J
    Gastroenterol Hepatol* (a different journal commenting on the Lancet case).

So PubMed's own record encodes a two-stage retraction history (partial 2004, full
2010) plus a separate expression-of-concern cross-reference that Crossref's single
`update-to` field (S2) does not surface at all — Crossref only knows about the 2010
full retraction DOI, not the 2004 partial one or the 2011 EOC. An agent relying on
Crossref alone for "has this been corrected before" would miss six years of history
that PubMed's `CommentsCorrectionsList` records explicitly.

How observed: 2026-10-12T20:58:19Z, curl, NCBI E-utilities efetch XML, keyless (no
API key sent; NCBI recommends one for >3 req/s, not required at this volume).

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
