How to read it
What research found: Did CBD help with this condition, did it not help, or are the results mixed?
Strength of evidence: How much can we trust this finding? From ●●●● strong to ○○○○ insufficient.
Many studies do not mean strong evidence. Example: Insomnia has 48 studies, but the evidence is weak.
Each topic’s page lists the studies we relied on.
