Commitment at a glance
Methodology version 2.0 · 18 August 2026
Source hierarchy
- Current guidance from recognized public-health and clinical authorities.
- Original peer-reviewed research and registered trial records.
- Authoritative datasets with methods and uncertainty ranges.
- Systematic reviews and evidence syntheses that disclose inclusion criteria.
- Community and implementation evidence when lived experience, access or delivery is the subject.
What every evidence record should show
- Original source and persistent identifier where available.
- Publication, update and access dates.
- Study design, population, geography, comparator and measured outcomes.
- Funding, declared conflicts, corrections, expressions of concern or retractions.
- What the evidence establishes, what it does not establish and where guidance differs.
Review and updating
Time-sensitive clinical and public-health pages are reviewed against the issuing authority's current version. Research pages distinguish publication date from the date the Center last checked the source.
A source becoming older does not automatically make it wrong. It does trigger closer review when the field, recommendation, product status or dataset changes.
Plain language without loss of meaning
Summaries remove unnecessary jargon but retain population, context, uncertainty and limitations. Numerical estimates keep their units, denominators and uncertainty where material. Early or preclinical findings are not described as established clinical benefit.
