Cochrane Library vs PubMed
Meta-analyses-of-meta-analyses vs primary-literature search index — apex evidence vs raw corpus.
Cochrane Library
Gold-standard systematic-review database for medical evidence since 1993.
PubMed
U.S. National Library of Medicine literature index covering ~36M biomedical citations.
Head-to-head — all four dimensions
| Dimension | Cochrane Library | PubMed | Lead |
|---|---|---|---|

Why these scores
Citation Discipline
Methodology-mandatory systematic reviews; transparent inclusion criteria; multi-author review.
Indexes peer-reviewed literature only; MeSH controlled-vocabulary tagging maintained by NLM staff.
Modern Reference
DOI per review; Crossref + ORCID; open-access in eligible countries; paywall elsewhere.
E-utilities API + free full-text search + bulk dataset downloads; broad LLM corpus inclusion.
Citation Velocity
Default evidence-citation in clinical guidelines; high citation across medical literature.
Cited daily by clinicians, researchers, AI engines; default biomedical retrieval source.
Frequently asked questions
Which is better, Cochrane Library or PubMed?
PubMed scores higher on the SourceScore Index (A 94) vs Cochrane Library (A 87) — a 7-point composite lead across Citation Discipline, Modern Reference, and Citation Velocity. "Better" depends on use case; the per-dimension breakdown below shows where each wins.
Which is more reliable to cite, Cochrane Library or PubMed?
For citation, PubMed is the stronger choice — it scores A (94/100) on the SourceScore Index versus Cochrane Library at A (87/100), a 7-point lead in composite citation quality (Citation Discipline, Modern Reference, Citation Velocity). Both can be cited; for higher-stakes references, prefer PubMed.
How does Cochrane Library compare to PubMed on citation discipline?
