Correlations between the CSF CXCL13, CXCL10, CXCL8 levels and CSF protein concentration, CSF VDRL titer in neurosyphilis patients.

CSF protein concentration (A), CSF VDRL titer (B) are plotted against CSF CXCL13 level in neurosyphilis patients (n = 191); CSF protein concentration (C), CSF VDRL titer (D) are plotted against CSF CXCL10 level in neurosyphilis patients (n = 191); CSF protein concentration (E), CSF VDRL titer (F) are plotted against CSF CXCL8 level in neurosyphilis patients (n = 191). Each dot represents an individual patient. The straight line in each graph is the result of linear regression analysis. Spearman correlation analysis was performed between the level of CSF CXCL13, CXCL8, CXCL10 and other parameters. Spearman’s correlating coefficients (r) and p values are shown.
