When Dr. Harrington reviews an article, he checks it against five questions. Tap each one to see what it means.

1Is it medically accurate?

Facts, figures, symptoms, causes and treatments are checked against reliable medical sources. Anything wrong or unsupported is corrected or removed.

2Does it match current guidelines?

Advice is compared with up-to-date guidance from national health services and professional medical bodies, so readers are not relying on outdated information.

3Are the warning signs clear?

Articles should say plainly when symptoms need urgent care or a visit to a doctor, and should never discourage anyone from getting professional help.

4Is it clear and easy to follow?

Medical terms are explained in plain language, so the guidance is useful to people without a medical background.

5Is it balanced?

No exaggerated claims, miracle cures or one-sided advice. Where evidence is limited or mixed, the article should say so.
