Cross tabulation showing statistical values for S100B and significant intracranial complications
SICC + Total = 24 SICC - Total = 488
S100B ≥ 0.10μg/L 24 350 PPV: 6,4%
Total = 374 (95% CI 4.2-10%)
S100B < 0.10μg/L 0 138 NPV: 100%
Total = 138 (95% CI 97-100%)
Sensitivity: 100% Specificity: 28%
(95% CI 83-100%) (95% CI 24-33%)

SICC = Significant intracranial complications, NPV= Negative predictive value, PPV= Positive predictive value.
