    "body_text": "Global discrimination scores can conceal whether a screening model overwhelms clinicians with false alerts. TRACER was pretrained on electronic health records from more than 4.5 million patients across four systems, then evaluated for 16 diseases at one-, two- and five-year horizons in over two million patients from two systems excluded from development. At 95 percent specificity, flagged patients were up to eight times more likely than unselected patients to receive a diagnosis within a year. Performance and alert burden still varied by disease and health system. The study demonstrates external evaluation, not readiness for clinical use or proof that earlier prediction improves outcomes.",
