AUC for ROC Analysis for Plasma GFAP, Tau, and Aβ42 in Complicated Mild TBI at Three Time Points After the Injury versus Controls

Biomarker	Day 0	Day 30	Day 90
GFAP	0.9360**	0.6425	0.7482^
Tau	0.9013**	0.8225**	0.6671
Aβ42	0.6887^	0.8362*	0.5543

^**p < 0.0001, ^*p < 0.001, ^p < 0.05.

AUC, area under curve; ROC, receiver operating characteristic; GFAP, glial fibrillary acidic protein; Aβ42, amyloid β peptide; TBI, traumatic brain injury.
