Design and validation of a recognition instrument—the stroke aid for emergency scale—to predict large vessel occlusion stroke

Receiver operating characteristic curves comparing the discrimination of NIHSS, SAFE, CPSSS, FAST-ED, RACE, and 3I-SS. (A) Receiver operating characteristic curves comparing the discrimination of SAFE, NIHSS, CPSSS, FAST-ED, RACE, and 3I-SS for the detection of large vessel occlusion strokes (all subjects). (B) Subjects with anterior circulation infarcts. (C) Subjects with posterior circulation infarcts. NIHSS: National Institutes of Health Stroke Scale; SAFE: Stroke Aid for Emergency Scale; CPSSS: Cincinnati Prehospital Stroke Severity Scale; FAST-ED: Field Assessment Stroke Triage for Emergency Destination scale; RACE: Rapid Arterial Occlusion Evaluation scale; 3I-SS: Three-Item Stroke Scale.
