Corrections.
An error is not quietly overwritten here. It is corrected, dated and made visible.
Reporting an error
Write to the address given on the Contact page. What helps: the address of the page concerned, the sentence objected to and, where available, the source that speaks against it. Reports about evidence take priority over everything else.
Deadlines
| Type of error | Response |
|---|---|
| Safety-relevant statement, emergency guidance | reviewed immediately, page temporarily toned down in case of doubt |
| Misreported study statement | within 5 working days |
| Wrong or dead source reference | within 10 working days |
| Spelling, wording, layout | on an ongoing basis, without a separate entry |
What a correction contains
- the date of the correction
- the version of the page
- the element corrected
- the reason for the correction
- the effect on the conclusion, named explicitly
- the responsible body
- the source that triggered the correction
Where a correction changes the conclusion of a page, it is flagged at the head of the page concerned and not merely listed here.
Retracted publications
If a work we have cited is retracted or has a warning attached to it, we review every page that uses it. Where the statement no longer holds without that source, it is removed or weakened. The process is documented here.

Once a month: new syntheses, checked studies, and what has changed in the state of the evidence.
