As shown in Fig. 6, no significant correlation was observed between miR-382-5p and NRG1 expression in RRMS, SPMS, NMO, and control groups (R = −0.2458, P = 0.3562), (R = −0.002, P = 0.9943), (R = 0.1092, P = 0.6467), and (R = 0.1144, P = 0.6311), respectively. This evidence concerns the gene NRG1 and neuromyelitis optica.
