Are all results peer reviewed?

Not necessarily. Database indexing and DOI registration do not guarantee peer-review status. Confirm the publication type and journal process on the original record.

Does a DOI prove that an article is high quality?

No. A DOI helps identify an object; it does not evaluate the study design, reporting quality, or whether the findings support your claim.

Can I search with a PMID?

Yes. You can use a PMID or DOI to locate a known record, or enter a topic when you need discovery rather than exact lookup.
