Figure 2

CXCL13 concentrations in the LNB and comparison CSF samples. Black diamonds indicate CSF samples with concentrations below the lowest standards of the assay (<7.8 pg/ml). If more than eight samples were below the lowest standard, the figure below the black diamonds indicates the number of such samples. The arrow indicates the median concentration. Kruskal-Wallis test followed by single pairwise comparisons with the Mann–Whitney U test and Bonferroni corrections were used for statistical analysis. **P < 0.01; ***P < 0.001.
