When a comparison gets something wrong, we fix it on the page and say so. This page explains how to report an error, how we handle it, and lists the corrections we have made.
Report an error
Use the form below. In the message, tell us which page, what is wrong and, if you can, a source that shows the correct information: a study on PubMed, a trial record on ClinicalTrials.gov, or a page from a regulator such as the FDA or WADA. We use your email only to tell you what we did.
You can also email [email protected]. We can’t answer personal medical questions.
How we handle a report
We read every report and check the page against the sources it cites and the source you sent. If the page is wrong, we correct it and add a dated line to the page’s change log saying what changed. We do not change facts silently.
If we find that the page is right, we keep it as it is. If you left an email, we tell you which source supports it.
What counts as a correction
A correction fixes something that was wrong or misleading when it was published: a figure, a trial count, a regulatory status, an evidence level, or a citation that does not support its sentence. Corrections are listed below and in the page’s change log.
Updates are different. When a new study is published or a regulator changes a status, we update the comparison and note the change in its change log, but we do not list it here, because the page was not wrong before. Changes that do not affect the facts, such as layout or link formatting, appear only in the change log.
