Figure 1. Peripheral blood leukocyte subset counts during dimethyl fumarate treatment.

Complete blood cell counts were obtained at baseline (n = 34) and at month 3 (n = 21), month 6 (n = 15), and month 12 (n = 17) of treatment. Red lines represent lower limit of normal for each subset. Statistical significance was computed using Mann-Whitney U test. p Values less than 0.05 were considered statistically significant. *p < 0.05; **p < 0.01; ***p < 0.001.
