How to read an evidence rating

Each research-observed effect on a profile is rated on the quantity, quality and consistency of published evidence. A rating describes the literature, not a recommendation.

Extensive
Multiple independent, well-designed studies, including human trials where they exist, consistently show the effect.
Moderate
Several studies document the effect, with limits such as small samples, animal-only data or no independent replication.
Preliminary
One to three studies, or mostly in vitro and animal data. Treat as exploratory.
Limited
Sparse or conflicting evidence. Mechanistic plausibility may exist but direct support is minimal.
