Study design details
Evidence Grade
Grade C: Limited Evidence
Evaluation of methodological rigor, population reach, and evidence alignment.
- Design Match
- Narrative review
- Risk of Bias
- High
- Consistency
- Not assessed
Strongest recorded design is a narrative review, drawn from 2 recorded studies, none of which measured an outcome in people.
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
