Figure 2. The individual change of CSF biomarker concentrations for boxers vs controls.

Figure 2

Cerebrospinal fluid (CSF) was collected from controls once. In boxers the CSF was collected 1–6 days after a bout (A) and after a rest period of at least 14 days (B). The figure illustrates the individual change of neurofilament light protein (NFL), glial fibrillary acidic protein (GFAP), S-100B and total-tau (T-tau). NFL in all controls expect one (380 ng/L) were below the detection limit of 125 ng/L, expressed as 125 ng/L on the chart. All controls had GFAP levels between 90–380 ng/L except the subject with elevated concentration of NFL.
