Evidence & sources

“Every claim cited” — how, exactly

Doctors are right to be skeptical of AI answers. This page is the audit trail: what goes in, how it is ranked, and what we refuse to do.

The pipeline
01 / Select

A curated, license-cleared corpus — not the open web. Guidelines, formularies and peer-reviewed literature are chosen source by source.

02 / Rank

Every source carries an authority grade in a fixed, visible hierarchy: Indian national guidance first, observational evidence last.

03 / Synthesize

Answers are generated only from retrieved passages. A claim without a resolvable citation is discarded, not published.

04 / Re-review

Guidelines get revised — so does the corpus. Sources are versioned and re-ingested when their publishers update them.

Source hierarchy

Ranked in the open

When sources disagree, rank decides what leads the answer — and the losing positions stay visible with their own citations. The hierarchy is fixed, published, and India-first by design.

When evidence is messy
Conflicting guidelines

All positions, side by side

Disagreement across sources is detected and surfaced — each position shown with its source and rank. The answer never hides a dissenting guideline to look cleaner.

Low confidence

A warning, not a guess

Where evidence is thin, the answer carries an explicit low-confidence banner and shifts source-forward — you read the evidence itself instead of a synthesized summary.

What EvidenceFirst is not
Not an EMR, and not a place for patient records
Not an AI scribe or documentation tool
Not a prescription generator
Not for patients — for verified clinicians and students
Not for emergencies — follow your institution’s protocols

EvidenceFirst supports — never replaces — clinical judgment. If an answer and your clinical assessment disagree, trust your assessment and check the sources.
