Sources and review status

Not medical advice and not for patient care. Questions are written from public sources and have not been reviewed by a clinician. Where a question has a verified source it is listed below and shown when you answer; where it has none, the game says so. Sources are cited as evidence for the fact. The wording is our own.

How a source is attached: we only list public links to authoritative sites (health agencies, national guideline bodies, major professional societies and journals) whose text was actually opened, and we say how much of it was read. A source here backs the specific teaching point; it does not mean the whole game is endorsed by that body. Spot an error? Use Report an error on the main menu.
