Diagnostic value of CSF CXCL13 in patients with definite LNB versus non-LNB. a CXCL13 concentrations in the CSF of pediatric patients with definite LNB versus control non-LNB patients. Black lines indicate medians. Values lower than the detection limit were arbitrarily assigned a value of 4.5 pg/ml. The dashed line indicates the optimal cut-off at 55 pg/ml. LNB Lyme neuroborreliosis. Means were compared by a Mann-Whitney test. ***P < 0.001. b Receiver-operating characteristic (ROC) curve of CSF CXCL13 levels from definite LNB patients versus control non-LNB patients. The dashed line indicates the optimal cut-off at 55 pg/ml. AUC area under the curve (95% confidence interval)
