Headline results
Every score is agreement with the clinical review panel, computed from what the plans share. Frontier models saw the patient's data only; Diadia has the panel's clinical knowledge built in.

Patient safety
Five ways a treatment plan can hurt a patient: starting a treatment too early, adding one the clinicians never prescribed, leaving out one they did, getting a dose wrong, and putting steps in the wrong order. Lower is better.

Patient safety
Patient-safety measures, Diadia against the frontier
Scores are agreement with the panel of practising clinicians who reviewed and signed off each plan, computed from the treatments the plans share. Thin lines show the likely range.
