  1. a The sex did not significantly differ between the groups as analyzed by Fisher’s exact test (C9orf72 vs. nonC9orf72 cases, p = 0.37; C9orf72 vs. healthy control cases, p > 0.99; nonC9orf72 vs. healthy control cases, p > 0.99)
  2. b The age did not significantly differ between the three groups as tested by one-way ANOVA (p = 0.43)
  3. c This column represents the number of cases with hypothalamus sections available that were screened for the presence of SCN-related neurons, SON and PVN
  4. VIP-ir neurons indicates vasoactive intestinal peptide-immunoreactive neurons; SON, supraoptic nucleus; PVN, paraventricular nucleus; SD, standard deviation
