Although there was no significant main effect of time on BDNF/IL-6 ratio (F(1,17) = 0.81, p = 0.38, ηp2 = 0.045), one bout of GXT resulted in a significant decrease in BDNF/IL-6 ratio in MS (p = 0.01), but not in controls (p = 0.74, Table 1, Figure 1e,f). This evidence concerns the gene BDNF and myeloid sarcoma.
