How we publish
Evidence is more useful when its limits are visible.
Each review separates published findings from interpretation, identifies the source type, and avoids turning research evidence into personal guidance.
Source attributed
Key claims point back to the documents or records that support them.
Evidence graded
Trial data, supporting documents, and self-reports are not presented as equivalent.
Boundaries stated
Limitations and research-use boundaries remain visible throughout.
Research-use boundary
Information for review—not medical advice.
RetaGrade materials are supplied for laboratory research use only. The library does not provide diagnosis, treatment, dosing, or authorization for human use.
