Writing about clinical evidence means being wrong sometimes. What matters is what happens next.
The policy
When something published here is factually wrong, it is corrected on the piece itself and recorded below. Corrections are not made silently. A reader who acted on the original version should be able to find out that it changed and why.
Three kinds of change are handled differently:
- Correction — a factual error in a claim, figure, citation, or clinical statement. The piece is amended, a note is added at the point of the error, and the change is logged here.
- Update — new evidence has changed a conclusion. The review is revised, the search date is updated, and the change is logged here.
- Clarification — the original was accurate but read ambiguously. The wording is adjusted and noted on the piece, without a log entry.
Typographical fixes that do not alter meaning are made without a note.
Reporting an error
If you find a mistake here, please send it in. Corrections raised by readers are credited unless the reader prefers otherwise. A clinician who takes the time to point out an error is doing this publication a favour, and it is treated that way.
The log
No corrections have been logged yet. Entries will appear here with the date, the piece, what was wrong, and what it now says.
