Scientific Claim Verifier

Graded evidence dossier for a scientific claim, from the PubMed literature.

Searches PubMed for a claim and returns an evidence grade (strong / moderate / limited / sparse) based on how many meta-analyses, systematic reviews and randomized trials address it, plus the top papers to read with links. The tool does the retrieval and grading of the evidence base; drawing the conclusion stays with you.
