TrialDiff

Open amendment evidence records

TrialDiff turns ClinicalTrials.gov amendment history into citeable evidence records: exact changed paths, source hashes, deterministic rules, timing context, and explicit claims-supported / claims-not-supported boundaries.

Source registry Repository & data Methodology
Severity is deterministic, reproducible, uncalibrated triage metadata, not validated review priority or proven wrongdoing. Evidence Records state what the registry history supports and what it does not support.
Case Study A: read an Evidence Record A compact secondary-outcome record with five changed paths, one outcome rule, and explicit non-claims. Case Study B: late-stage timeline movement A 731-day timeline movement surfaced by deterministic triage without asserting intent or wrongdoing.
