Within both (inactive and active) type of MS patients, correlations between number of CELs and all other biomarkers were analyzed using Spearman analysis; And then only for statistically significantly (p < 0.01) correlated biomarkers linear regression with number of CELs as a dependent variable was analyzed: IL-12p40 (Rho = 0.66, R2 = 0.36, and p < 0.0001), cNfL (Rho = 0.62, R2 = 0.31, and p < 0.0001), CXCL13 (Rho = 0.42, R2 = 0.12, and p = 0.0067) and CHI3L1 (Rho = 0.54, R2 = 0.22, and p = 0.0001) (Figure 4 and Supplementary Table 2). This evidence concerns the gene CXCL13 and myeloid sarcoma.
