Figure 1. Distribution of Plasma Biomarkers (Ln Transformed) Among Participants With mTBI at <6 Hours and 7 Days Postinjury in Comparison With Control Participants.

Compared to uninjured controls, plasma levels of GFAP (A), UCH-L1 (B), and IL-6 (D) were significantly elevated in mTBI <6 hours, while NfL levels (D) were elevated at 7 days. GFAP = glial fibrillary acidic protein; IL = interleukin; mTBI = mild traumatic brain injury; NfL = neurofilament light chain; UCH-L1 = ubiquitin carboxy-terminal hydrolase L1.
