FIG. 3.

Receiver operating-characteristic curve comparing performance of plasma glial fibrillary acidic protein (GFAP) and serum S100 calcium-binding protein B (S100B) as biomarkers for predicting intracranial injury on head CT scan within 24 h of injury across the full spectrum of traumatic brain injury (TBI) (Glasgow Coma Score [GCS] 3–15). The area under the curve (AUC) demonstrates that GFAP significantly outperforms S100B. GFAP measurements were performed on a point-of-care platform prototype assay capable of returning results within 15 min. Color image is available online.
