Understanding our evidence ratings

Evidence ratings reflect the quantity, quality and relevance of published research.

Substantial Multiple human studies, or at least one well-controlled human trial plus supporting evidence.
Moderate Some human evidence exists, but study size, replication, or quality is limited.
Preliminary Mostly preclinical, in-vitro, animal, or small exploratory human evidence.
Insufficient Not enough evidence specific to this use to draw a meaningful conclusion.
