How the ratings work
- Strong
- Consistent results across many randomized trials, pooled in at least one meta-analysis.
- Moderate
- Meta-analyses or several trials point the same way, but with real caveats (small studies, mixed quality, wide uncertainty).
- Limited
- A small number of small or early studies. Promising or plausible, not established.
- Insufficient
- Little or no credible research for the claims usually made.
A rating describes the strength of evidence for a specific outcome, not whether a technique is pleasant or worth trying. Every study is opened and read at its source, and findings are stated no more strongly than the study states them. Pages are checked by Beiing's editorial and research team, not by licensed clinicians. How to read health evidence ยท For clinicians
