PORTRAIT: a calibrated patient ‘Passport’ with built-in refusal - describing individuals against a reference population

2026-07-15

Abstract excerpt

<h4>Background</h4> Average-based summaries serve individual patients poorly. PORTRAIT is a calibrated, abstention-aware tool that describes where one patient sits relative to a reference population across 12 cardiometabolic markers, how confident that placement is, and which features drive it. PORTRAIT describes; it does not diagnose or predict. Abstention is a designed feature given the known limits of conditio...
