Median serum concentrations related to non-traumatic intracranial findings
| Non-traumatic findings | Patients with non-traumatic lesions |
Patients without non-traumatic lesions |
p-value | ||
|---|---|---|---|---|---|
| n (%) | S-100B concentration (μg l−1) | n (%) | S-100B concentration (μg l−1) | ||
| Chronic parenchymal defect (s.p. infarction or trauma) | 12 (30.0) | 0.50 (0.31–0.70) | 28 (70.0) | 0.27 (0.08–0.62) | 0.09 |
| Brain atrophy | 17 (42.5) | 0.47 (0.29–0.84) | 23 (57.5) | 0.22 (0.07–0.53) | 0.02 |
| Microangiopathy | 12 (30.0) | 0.55 (0.32–0.83) | 28 (70.0) | 0.27 (0.08–0.57) | 0.06 |
s.p., status post concentrations are given as median (interquartile range). Mann–Whitney U test was used to compare different S-100B concentrations. The cut-off value of serum concentrations was 0.1 μg l−1.
