  1. Wilcoxon signed ranks test was use and analyzed by disease group. Other variables measured that are not significant (i.e. p > 0.05) is not listed in the table. No significant changes were observed to any variables in the SPMS group over time. The EDSS was stable with little changes in both RRMS and SPMS shown in Table 1. Concentrations of all the inflammatory mediators are expressed in picogram per mililter (pg/ml).
