Figure 3. Correlations between the CSF IL-17 levels and the CSF protein levels, CSF WBC counts or CSF VDRL titer of neurosyphilis patients.

CSF protein levels (A), CSF WBC counts (B) and CSF VDRL titer (C) are plotted against CSF IL-17 level in neurosyphilis patients (n = 103). Each dot represents an individual patient. The straight line in each graph is the result of linear regression analysis. Spearman's correlation coefficients (r) and P values are shown.
