Table 3 shows the cytokine levels according to patient group. In HAM/TSP patients, a significant negative correlation was detected between TNF-α and vitamin D levels (r = −0.272; p = 0.009). Figure 1, Figure 2 and Figure 3 show these findings. Values for cytokines levels are also depicted in Table 4. This evidence concerns the gene TNF and tropical spastic paraparesis.
