Accuracy is an ongoing responsibility. We review credible reports of factual errors and correct material mistakes on the affected page. A correction note should explain what changed and when. Minor spelling or formatting fixes that do not alter meaning may be made without a formal note.
Request a correction
Use our contact page and include the article URL, the passage in question and a reliable source or other evidence. Please do not send private medical details unless they are necessary to explain the issue. We may need time to check a claim with its original source.
What happens next
We assess whether the information is inaccurate, incomplete, outdated or simply open to interpretation. If a change materially affects the article, we update the copy and add a dated explanation. A substantial clinical change also returns to the appropriate review process. Our editorial standards describe the wider approach.
