How we maintain the corpus
Our knowledge base is curated, versioned, and refreshed on a recurring cadence. Every agent response is anchored to the underlying source so clinicians and patients can verify the basis of any recommendation.
Peer-reviewed only
We exclude pre-prints, opinion pieces, and non-indexed content from the production corpus.
RAG architecture
Retrieval-augmented generation ensures answers are anchored to specific sources, not model memory.
Versioned updates
Corpus snapshots are tagged so a given clinical recommendation can be reproduced at the source level.
Clinical review
New sources are reviewed by bariatric clinicians before being added to the production index.
The PDFs linked above contain the full reference list per agent corpus. The citations on this page represent the most frequently cited and highest-evidence sources identified by analysis of each corpus.
