Editorial method
How pages are written, sourced and labelled.
What we do and don’t
We do
- Explain how the body works and how conditions arise.
- Source every medical section; rate evidence where effectiveness is claimed.
- Separate available, in-trial and preliminary.
- Say clearly when evidence is insufficient.
We don’t
- Diagnose.
- Give doses.
- Show probabilities without a validated model.
- Invent studies, statistics or FAQs.
Source tiers
| # | Tier | Examples | In registry |
|---|---|---|---|
| 1 | Health agencies & guidelines | WHO, NIH, NHS, FDA, ADA, KDIGO | 735 |
| 2 | Systematic reviews | Cochrane | 11 |
| 3 | Peer-reviewed original studies | NEJM, BMJ, Lancet, Diabetes Care | 5 |
| 4 | Educational & historical references | NCI SEER Training, NLM, Britannica, Nobel Prize | 128 |
Every complete page needs 2+ references, one from tier 1. Text is fully rewritten rather than copied from sources; numbers, formulas and reference ranges are kept exactly as their sources publish them.
Evidence scale
GRADE levels are used where effectiveness is claimed.
- Strong evidenceHigh confidence that the true effect is close to the estimate; usually based on large, consistent randomised trials or systematic reviews of them.
- Moderate evidenceThe true effect is probably close to the estimate, but new research could change it.
- Limited evidenceLimited confidence; the true effect may differ substantially from the estimate.
- Very low evidenceVery little confidence; the estimate is highly uncertain.
- Preliminary researchLaboratory, animal or very small human studies — not enough for a clinical recommendation.
- Under studyAn open question under study, with no conclusive results yet.
Technology maturity
A separate scale for technologies.
- In widespread clinical use
- Approved for specific uses
- In clinical trials
- Preclinical
- Concept
Review status
- Edited content
- Editorially reviewed
- Medically reviewed
All current pages carry the status “Edited content”.
How a page is built
- Pick 2+ sources.
- Write with the template at three levels.
- Attach sources and evidence grade.
- Write weighted, sourced relations.
- Run the validator; any error stops the build.
- Preview on mobile and dark mode.
- Record review status and date.
