Meta Help Center

One reason you may get more results in Meta than in PubMed is because Meta includes preprints from bioRxiv. Second, Meta uses machine learning to scan new biomedical articles, analyze and incorporate them into a dynamic map of biomedical concepts—every journal, researcher, disease, gene, protein, pathway, protocol and more. This allows Meta to capture much more information about a paper than keywords. Third, Meta may expand your search queries to include related concepts or terms, and therefore return more results.
