How to report an error
Provide the page URL, the exact statement or interaction you believe is wrong, the reason, and a reliable supporting source. Use the Contact page for the current channel status; never send medical records or other sensitive personal data.
How updates are assessed
The editorial team checks the cited evidence, publication date, population, outcome, and whether the issue changes the practical meaning of the page. A disagreement is not resolved by hiding the original source or inventing an expert quotation.
How updates are shown
Substantive factual changes should update the modified date and include a correction note. Minor spelling, formatting, or accessibility repairs do not receive artificial freshness signals.
