Figure 5

Receiver operating curve (ROC) showing sensitivity and specificity of cerebral glucose changes combined with presence of fever ≥ 38°C for diagnosis of bacterial meningitis. Twelve patients with aneurysmal subarachnoid haemorrhage (SAH) and meningitis undergoing microdialysis measurement at the time of diagnosis and 136 without infections of the central nervous system were included. Data are given for maximum glucose decrease over variable time spans within the observation period. Area under the curve (AUC) = 0.74, standard error = 0.08 (p = 0.004 compared with null hypothesis with AUC = 0.5). Blue line: Sensitivity and specificity of cerebral glucose changes with fever for diagnosis of meningitis; green line: sensitivity and specificity for null hypothesis.
