Expression of concern

A formal post-publication notice issued by a journal to alert readers to substantive concerns about a published article when the journal cannot yet conclude that retraction or correction is the appropriate outcome. An expression of concern is appropriate when concerns are credible but unresolved, often pending an institutional investigation.

Examples

Worked examples

Counter-examples

Looks similar, but isn't

  • Not an instance

    A journal issuing a retraction with a clear finding of fabrication, which supersedes any earlier expression of concern.

Editorial commentary

Expressions of concern (EoCs) are intended as interim measures, not as a permanent endpoint. COPE recommends that EoCs be replaced by either a correction or a retraction once the underlying investigation concludes; in practice many EoCs remain unresolved for years because institutional processes stall or are not transparently reported back to journals. Like retractions, EoCs are indexed in CrossRef and PubMed and should be linked bidirectionally to the original article.
