1 of 34 checkable references need attention · checked 2026-07-22
At the dated check, the references listed below either did not resolve in
Crossref or DataCite, or carried a retraction notice. Each one is shown with the
registry record that put it there.
19 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. It says nothing about the quality, findings,
or importance of the work itself, and nothing about references deposited without a DOI.
