Hello,

I have an article with a PMC ID: PMC11614110. I know there are articled that are only indexed in PMC but for the journal (Acta Crystallographica Section F) I would normally expect a PubMed ID as well. However, running a query on the article API returns only the PMC ID.

Am I missing something?

Thanks

Melanie

Dear Melanie,

It appears that, despite the journal’s inclusion in PubMed’s index, this particular article was never assigned a PMID. As a result, no PubMed   identifier exists in either PubMed or on the PMC record (see https://pmc.ncbi.nlm.nih.gov/articles/PMC11614110/).
The underlying cause is unknown to us; only PubMed can provide an explanation for why this entry was omitted.  

Please let me know if you have any further questions.

Yours sincerely,
Islam Hassan

Dear Melanie,

The standard process would be to reach out to NCBI's helpdesk and explain the problem.
They can be contacted through:
