How evidence grades work

Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.

Strong
Multiple RCTs, consistent direction, adequate effect size
Moderate
Some RCTs or consistent observational data in humans
Preliminary / Mixed
Animal or in-vitro only, or conflicting human data
Traditional / Theoretical
Traditional use only; no controlled human trials

A 2023 systematic review and meta-analysis reported that azapirones as a class outperformed placebo for generalized anxiety disorder across 22 studies involving 2,567 participants, with evidence confidence varying by comparator.

Background
Meta-analysis

Statistically combines results from multiple eligible studies; confidence still depends on the quality, consistency, and directness of those studies.

A 2006 Cochrane review of 36 randomized trials involving 5,908 participants concluded that azapirones, including buspirone, were superior to placebo for generalized anxiety disorder, while comparative evidence against other treatments was less certain.

Background
Systematic review

Uses a predefined method to find and evaluate relevant studies, but may or may not pool their results statistically.

A 12-month multicenter open-label study of 700 patients with generalized anxiety disorder reported symptom improvement and generally favorable tolerability during buspirone maintenance treatment.

Background
Other / unclear

The study design is not yet classified clearly enough to infer its place in the evidence hierarchy.
