From: CXCL13 chemokine as a promising biomarker to diagnose neurosyphilis in HIV-negative patients
Receiver operating characteristics (ROC) curve analysis using CSF CXCL13 and QCXCL13 for discriminating neurosyphilis from non-neurosyphilis/syphilis. a CSF CXCL13 yielded an AUC (the areas under the ROC curve) of 0.831 (95 % CI 0.724–0.938, P = 0.000) with 80.0 % sensitivity and 81.4 % specificity in discriminating neurosyphilis from non-neurosyphilis/syphilis. b QCXCL13 yielded AUC of 0.758 (95 % CI 0.620–0.895, P = 0.001) with 87.5 % sensitivity and 69.2 % specificity in discriminating neurosyphilis from non-neurosyphilis/syphilis
