Every reference with a DOI in the deposited reference list resolved to a known
work in Crossref or DataCite at the dated check, and none carried a retraction,
withdrawal, or removal notice.
5 without a DOI — not checked. A reference
deposited without a DOI is never matched by title or guessed at; it stays outside the checked
set, and this line discloses that.

What this badge says. CiteStamped means the CHECKABLE references of this
work were clean at the dated check: each resolved to a known work in a public registry, and none
carried a retraction notice at that time. If Crossref’s record marks the work itself
retracted, withdrawn, or removed, the badge says so instead of showing clean. It says nothing
about the quality, findings, or importance of the work itself, and nothing about references
deposited without a DOI.
checked 2026-08-08 — re-checked at most once a day, when someone opens
this page, so the date shown is the last check; titles and statuses come from Crossref and DataCite and are not
part of the signed record
Both snippets point at the live badge image and link back to this page. The
badge shows the date of its last check, which runs at most once a day, when someone opens this page.
