Comparison of CSF Nf-L levels between healthy calves and those (age, 2–12 months) with a CNS infectious/inflammatory disorder. CSF Nf-L levels were significantly higher in calves with an infectious/inflammatory disorder. The median, IQR, maximum and minimum are shown. The Mann–Whitney test was applied. Asterisks (*) denote the level of statistical significance: **** p < 0.0001. CSF denotes cerebrospinal fluid, CNS central nervous system, IQR interquartile range, Nf-L neurofilament light chain.
