FIG 1.
(A) CXCL13 concentrations in CSF determined by CXCL13 ELISA in different disease groups. Levels of CXCL13 in CSF of patients with definite and possible LNB were determined by CXCL13 ELISA. Non-LNB patients were stratified according to disease group. The horizontal lines indicate medians. Values lower than the detection limit were given a value of 4.5 pg/ml. The dashed line indicates the optimal cutoff value of the CXCL13 ELISA (78.6 pg/ml). VZV, varicella-zoster virus; HSV, herpes simplex virus; BM, bacterial meningitis; MS, multiple sclerosis; EV, enterovirus; TBEV, tick-borne encephalitis virus; MM, malignant melanoma. (B) CXCL13 concentrations in CSF determined by CXCL13 LFA in different disease groups. The dashed line indicates the optimal AV cutoff of 22.5.
