Methodology

Evidence Engine v1.0 — Phases 1-2 are LLM-free (pure API queries). Phase 3 uses LLM to classify papers as supporting/contradicting/neutral. Phase 4 actively searches for contradicting evidence. Grounded confidence is computed from evidence pyramid weights, citation counts, recency, and support ratios — not extracted from LLM-generated text.

APIs used: PubMed E-utilities, Semantic Scholar, ClinicalTrials.gov, Europe PMC
Evidence pyramid weights: Systematic Review (1.0) > RCT (0.85) > Clinical Trial (0.70) > Cohort (0.55) > Review (0.40) > Case Report (0.30) > Preprint (0.25)
