Which AI gives the best care-plan second opinion?

Handed a real plan — medications, protocols, lifestyle guidance — which model finds the highest-impact change without inventing one? Clinicians score that blind, on their own patients' de-identified charts.

The question every model answers: “Review the current plan (medications, protocols, lifestyle guidance) against this patient's data. What would you keep, change, or add — and what is the single highest-impact adjustment?
