Health information is only useful if it's accurate. That's why clinical content on Zerunio is checked by qualified medical professionals before it reaches you.
Who reviews our content
Medical reviewers are licensed clinicians – physicians, pharmacists, nurses, and specialists – verified against national registries and medical councils. A reviewer is matched to the article by expertise, so a cardiologist reviews heart content and a pharmacist reviews medication content.
What the review covers
- Every clinical claim is checked against primary sources and current guidelines (NHS, WHO, CDC, NICE, peer-reviewed literature).
- Reviewers confirm the article is accurate, balanced, and safe, and flag anything that needs a clinician's input.
- Reviewed articles carry a "medically reviewed by" line and the reviewer's profile.
How we grade evidence
Not all evidence is equal. Where an article rests on a specific body of research, we label it with an evidence grade shown as a badge near the byline, so you can see how strong the underlying evidence is.
| Grade | What it means |
|---|---|
| Systematic review | Synthesis of all relevant studies (meta-analysis / Cochrane review). The strongest tier. |
| Randomized trial | One or more randomized controlled trials – the gold standard for testing whether a treatment works. |
| Clinical guideline | Recommendations from an authoritative body (NICE, WHO, CDC, a specialist society). |
| Observational study | Cohort or case-control research showing associations, not proof of cause and effect. |
| Expert opinion | Consensus or expert judgement where higher-tier evidence is limited. We say so plainly. |
Two further labels appear when an article has no explicit grade: Clinician-reviewed (a credentialed clinician signed off) and Cited sources (every claim links to a primary source).
Keeping content current
Articles are scheduled for periodic re-review and updated when evidence or guidelines change. The last-reviewed date appears on each article.
Community & AI
In the community, only verified doctors can post answers. AI answers (MediMind) are clearly labelled, carry a disclaimer, and are ranked as general information – never as a substitute for a clinician.
