Application developer: Lunit Inc., Seoul
Role: Not assessed
Configuration: Not assessed
Inputs and outputs: Not assessed
Autonomy: Not assessed
Workflow: AI chest-radiograph triage at a peripheral emergency service. Radiographer-performed screening ultrasound to confirm.
Human oversight: Not assessed
Relation to AI: The AI flagged the effusion correctly but with lower confidence on the subpulmonic side. Ultrasound confirmed it. The source is a non-vendor case report with no financial support declared. The outcome did not follow because the patient declined care.
AI contribution: The AI flagged the effusion correctly but with lower confidence on the subpulmonic side. Ultrasound confirmed it. The source is a non-vendor case report with no financial support declared. The outcome did not follow because the patient declined care.

Outcome identifiers: Not assessed
Benefit: At a basic emergency service in the Algarve, the AI marked bilateral effusion (97% left, 77% right); screening ultrasound confirmed a right subpulmonic effusion; the patient refused transfer and left.

Conditions for replication: Clinicians check lower-confidence AI flags with ultrasound. Patients accept referral.
Replication attempts: Not assessed
Later findings: The patient refused transfer and left against medical advice; the cited case report describes no follow-up and no comparison of the AI flag against a radiologist reading, since no over-read was obtained.
