Abbreviations: AUC = area under the receiver operating characteristic; CV = cross-validation; GFAP = glial fibrillary acidic protein; IL = interleukin; LOC = loss of consciousness; mTBI = mild traumatic brain injury; NfL = neurofilament light chain; PTA = post-traumatic amnesia; UCH-L1 = ubiquitin carboxy-terminal hydrolase L1.
Seven days AUC values were determined using the same control results used for <6 hours.
