HOW EVIDENCE IS GRADED
Two evidence lines. One shared scale.
Preclinical evidence
Cell, animal, mechanism, and translational research—kept separate.
1/5 · Very limited
2/5 · Early
3/5 · Developing
4/5 · Substantial
5/5 · Mature
Bars describe evidence depth—not effectiveness, safety, product quality, or personal suitability.
WHAT CHANGED
Freshness should be inspectable.
New source events and record revisions keep their dates, primary sources, and evidence boundaries visible.
