Fig. 3From: BAFF Index and CXCL13 levels in the cerebrospinal fluid associate respectively with intrathecal IgG synthesis and cortical atrophy in multiple sclerosis at clinical onsetCorrelations between BAFF Index and intrathecal IgG synthesis. A mild correlation between BAFF Index and intrathecal IgG synthesis was observed when all the patients were considered (a–c). The correlation was strong when the null values of intrathecal IgG synthesis were excluded (a’–c’)Back to article page
