NEFM and amyotrophic lateral sclerosis: The post hoc analyses (n = 6, Bonferroni correct p‐value of 0.0083) showed a significant decrease in gyration in ALS compared with controls for non‐phosphorylated NfH (p < 0.0001) and NfM (p < 0.0001), as well as for their simulated phosphorylated states pNfH (p<0.0001), pNfM (p < 0.0001).
