Confidence levels

Not every prediction is equally well-supported. Lab tells you which is which.

High confidence

• Multiple human RCTs
• Clinical use widespread
• Most prescription drugs at standard doses

Medium confidence

• Limited human data or only observational
• Mechanism is well-understood from animal work
• Common supplements at typical doses

Low confidence

• Animal-only or in-vitro only
• Theoretical extrapolation from mechanism
• Lab plots these with wider confidence bands and warns you

Where you'll see this

• In the Bibliography — every source carries a confidence badge
• In the inspector — the citation pills on every row use a separate but related color language: green = cited, blue = calibrated, red ⚠ = uncited. Hovering a pill shows the underlying source's confidence
• In charts — lower-confidence predictions get wider confidence bands
