When doesn't MEDRS apply?
It's important to be careful, but don't panic. Not every statement in a biomedical article requires you follow the MEDRS guidelines.
MEDRS does not apply to statements that don't touch on human biomedical topics, even if the statement appears within a biomedical-related article.
Oftentimes, this level of sourcing would be inappropriate or impossible, and could actually stand in the way of writing a strong article.
- A sentence in the "culture" section of the "Black Death" article describing its impact on 14th-century religious fervor in Europe.
- A "history" section within the "Opium" article, describing its use in ancient times.
- A "popular culture" section mentioning that the fictional protagonist of the spy-thriller series Homeland was diagnosed with bipolar disorder.
Though you should always use the best-quality sources you can find, these types of statements do not require MEDRS.
