Sources
Every quantitative or factual claim on the registry traces to one or more entries in the registry-wide source list. The rules below define what counts as a source for each claim type.
Source object
Each source has a stable kebab-case slug, a URL, a title, a publisher, the date it was accessed, and a Wayback Machine archive URL where the original is non-government / non-regulator. Sources are catalogued in src/content/sources.json.
Per-claim-type rules
- Accreditation status
- Accepted: the issuing body’s public directory listing. Not accepted: clinic logo on its own marketing page.
- Corporate registration
- Accepted: the national company registry filing (UK Companies House, Hungarian e-cégjegyzék, Thai DBD, etc.) with the registration number visible.
- Surgeon registration
- Accepted: the relevant medical or dental council’s public register, specifically the URL where a reader can verify the registration number.
- Outcome rates (complication, revision, mortality)
- Accepted: peer-reviewed publications with DOI; recognised national outcome registries (e.g. NJR, CMS, HFEA, SCTS); meta-analyses from named authors. Not accepted: clinic self-reported figures without independent audit.
- Prices

Currently in scope
The registry-wide source list contains over 120 entries. As editorial proceeds through the tier-1 / tier-2 evidence checks for every clinic, this list grows. Consumers can pull the source list via the public API at /api/sources (in scope for Phase 11).
