Medical research from 12 databases — in your language.
One search across PubMed, Europe PMC, Cochrane, ClinicalTrials.gov, J-STAGE, LILACS, HAL, ThaiJO, KoreaMed and more — from the US, England, Europe, Japan, Brazil, Thailand, France, Korea and beyond. Titles and abstracts translated as results arrive. Every record links back to the original source — we don't grade, rank, or advise.
Semaglutide and Cardiovascular Outcomes in Patients with Heart Failure and Obesity
Smith et al. · n = 4,263 · 24-month follow-up
Triangulated
Confirmed by 3 ClinicalTrials.gov entries (NCT04788511, NCT05076669) and a 2023 medRxiv preprint with concordant effect size.Surface the patterns you didn't think to look for.
After every search, Symmathy reads the full result set as a whole and flags signals a human skim usually misses — recurring co-mentions across studies, contradictions between trials on the same question, subgroup effects buried in the abstracts, adverse-event hints, and endpoints you'd expect to see measured but nobody reports. Every insight cites the exact records and quotes it came from, so you can verify it in one click. Symmathy never grades the papers — it just helps you notice what's there.
Example insight
3 of 8 semaglutide trials excluded patients with eGFR < 30 — renal subgroup is unrepresented.
Evidence: NCT04788511 · "excluded if eGFR <30 mL/min" · Smith 2024 · +2 more
Global evidence
Medical data from around the world.
Most evidence engines stop at English-language Western journals. Symmathy pulls from regional indexes too — so studies from the United States, England, Europe, Japan, China, Brazil, Israel, India, and across Africa and the Middle East all surface side by side.
Non-English abstracts are translated on the fly; every record links back to its original source so you can verify the primary text.
PubMed / MEDLINE

Europe PMC
MEDLINE, PMC, bioRxiv, medRxiv — a European mirror with extras.
Cochrane Library
Systematic reviews synthesizing trials from every continent.
J-STAGE
Japanese biomedical journals, English & Japanese abstracts.
LILACS
BVS / BIREME — Brazilian, Argentine, Mexican, Chilean health research.
HAL
French national open archive — life sciences, public health, INSERM.
OpenAlex
Chinese, Thai, Israeli, Middle-Eastern, and African journals.
DOAJ
Vetted open-access journals worldwide — strong on Africa & Asia.
CrossRef
Broadest scholarly metadata index — deduplicates across publishers.
ThaiJO
TCI health-sciences journals — harvested nightly from per-journal OAI-PMH feeds.
KoreaMed
Korean Association of Medical Journal Editors index — JKMS, KJIM, and ~250 other Korean biomedical journals.
Workflow
Three ways to interrogate the literature.
Scan a PDF
Drop a paper. Symmathy extracts study design, population, endpoints, effect sizes, risk-of-bias signals, and funding sources — preserving page-anchored citations.
Federated search
One query, fanned out across PubMed, Europe PMC (incl. bioRxiv & medRxiv), the Cochrane Library, ClinicalTrials.gov, J-STAGE, LILACS, DOAJ, HAL, OpenAlex, CrossRef, and ThaiJO. Filter by study type, population, year, and evidence grade.
Compare & triangulate
Drop in 2–20 studies. Get a side-by-side of methods, populations, and outcomes — with a knowledge-graph view of corroborating and contradicting evidence.
The next paper on your desk could change a guideline.
Start with a single PDF. Symmathy handles the rest.
