About this index

Who runs it

The Transparency and Trust Index is operated by Trail Digital, based in Cape Town, South Africa. A digital marketing agency. See the About page for the independence and conflict of interest policy.

What it is

An open-methodology index of health practices. It scores publicly verifiable facts, shows the evidence for each one, and publishes the method. It does not measure clinical quality. See the methodology.

Funding and independence

• There is no commercial model. The index has no adverts, paid placement, referral fees, commissions or lead capture.
• No practice has paid or can pay to be listed, removed, or to change a score.
• Scores change only when the underlying public data changes or the published methodology changes. Both are logged in the changelog.

Conflict of interest

Trail Digital is a marketing agency. If a listed practice is a client of Trail Digital, its page says so, and the practice is researched and scored by exactly the same rules as every other practice.
