Table 3 Serum GFAP and UCH-L1 concentrations in cases stratified by neuroimaging results.

From: Serum Concentrations of Ubiquitin C-Terminal Hydrolase-L1 and Glial Fibrillary Acidic Protein after Pediatric Traumatic Brain Injury

   N GFAP (ng/mL) UCH-L1 (ng/mL)
Cases Positive CT (ICI) 29 0.73 (0.15–2.28) +++ 0.44 (0.17–0.99) +++
Skull Fracture Only 6 0.58 (0.09–1.59) ++ 0.14 (0.08–0.22) +*
Negative CT 10 0.21 (0.08–1.37) +++ 0.14 (0.08–0.27) +**
  1. ICI = intracranial injury. Symbols indicate statistical difference of the Mann-Whitney test for differences between groups: vs Controls (+++) p < 0.001, (++) p < 0.01, (+) p < 0.05; vs Positive CT (*) p < 0.05, (**) p < 0.01.
