Serum S100B Levels Can Predict Computed Tomography Findings in Paediatric Patients with Mild Head Injury

Figure 3

S100B serum concentrations according to patient GCS scores upon admission to the emergency department. This graph groups the median (and interquartile range) serum S100B concentrations according to the patients’ initial GCS scores upon their admission to the emergency department. The black squares indicate the concentrations of the patients without cranial injury (CT−), and the open squares indicate the concentrations of the patients with cranial injury (CT+). S100B concentrations were significantly increased in the patients with cranial injury (CT+) compared with those in the patients without cranial injury (CT−) in each GCS group ( in the test, CT+ versus CT−). Among the patients with cranial injury (CT+), S100B concentrations in the patients with GCS scores of 15 were significantly lower than those in the patients with GCS scores of 13 or 14 ( in ANOVA followed by Dunn’s post hoc test for multiple comparisons). Among the patients without cranial injury (CT−), no significant differences were observed in S100B concentrations in the patients with GCS scores of 13, 14, or 15.
