Evidence dossier · candidate cand-mmr-pharyngitis · VICP program · · DRAFT — not a determination
This is a draft research-tracking dossier, not a determination that MMR vaccine causes Pharyngitis, and not an incidence or legal finding. All evidence is flagged needs_human_review and must be reviewed before any page is published or cited. Every value is grounded in retrieved citations (PMID + retrieval date); unsourced items read "no evidence found / not assessable". Symmetric search: every supporting query has a mirror/null query, and zeros are shown (negative dossiers report the absence of signal).

Two evidentiary bars apply to the epi nodes/claims (C3, C4): · VICP — preponderance of the evidence. · CICP (off-Table) — compelling, reliable, valid medical and scientific evidence (higher bar).
Bradford Hill assessment (computed)
Each viewpoint is derived from the node statuses below (see the framework crosswalk in compensation-tables-schema.md §8). Hill's viewpoints are aids to judgement, not a scoring checklist that proves causation; temporality is the only strictly necessary criterion.

NASEM (formerly IOM), "Adverse Effects of Vaccines: Evidence and Causality" (2011, updated 2024). Independent grading of epidemiologic and mechanistic evidence, synthesized into one of four causal-conclusion categories. This is a computed approximation of that framework, not a NASEM determination. See compensation-tables-schema.md §8bis.
Case-definition standard: no established case definition (needs_human_review — not in spec §1's named-standard list) — governs the case-certainty scale on A1/A2/A6/A8 below. See compensation-tables-schema.md §8ter.

How this was built
Per node: a supporting and a mirror PubMed query built from the node's measure / population / comparator / hit_rule; top hits fetched (title + abstract); each record classified (supports / refutes / ambiguous) by xAI with a heuristic fallback; a per-node synthesis is generated strictly from the retrieved PMIDs; the node status is then rolled up to C1–C6. Full query provenance is shown per node above. Reproduce the build: python -m evidence_run. Data: data/evidence_run/state.json.
