Figure 4. CSF-serum ratio of KFLC (Q KFLC) among different oligoclonal IgG band patterns.

Figure 4

There are five classic patterns of oligoclonal bands [48] (type 1, no bands in CSF and serum; type 2, oligoclonal IgG bands in CSF but not in serum, indicative of intrathecal IgG synthesis; type 3, oligoclonal bands in CSF plus identical oligoclonal bands in serum and CSF, indicative of intrathecal IgG synthesis; type 4, identical pattern of oligoclonal bands in CSF and serum. There was no patient with type 5 (identical patterns of monoclonal bands in CSF and serum) in the study. Horizontal solid line indicates median, Kruskal-Wallis test among groups revealed a significant difference (p<0.001), significant P-values for pairwise comparisons (Mann-Whitney U test) are displayed.
