How a byline works here

A named writer signs the guides they wrote. The editors sign the site's own pages, such as the topic pages and the policies. Nobody on this site is presented as a doctor, and no page claims a medical review: health facts link the official page or study they come from instead, so you can check them yourself.

To report an error in any guide, use the contact page. Corrections follow our editorial policy.
