Box plots of CSF CXCL13 concentration (Figure 1A) and serum CXCL13 concentration (Figure 1B) in three patient groups. Patients with symptomatic neurosyphilis (Symptomatic NS) had hearing or vision loss with or without cerebrospinal fluid (CSF) abnormalities. Patients with asymptomatic neurosyphilis (Asymptomatic NS) had CSF white blood cells > 20/uL or a reactive CSF-VDRL or both, but no hearing or vision loss. Patients with uncomplicated syphilis had no hearing or vision loss, CSF white blood cells < 20/uL and nonreactive CSF-VDRL.
