Relationship between SEED’s SS detections, age, and sex on NSRR6. (a-d) To show age effects, subjects were grouped using 5-year intervals. For each age group, the following SS parameters are shown: (a) Mean duration. (b) Mean PP amplitude. (c) Mean spindle frequency. (d) Spindle density. (e–h) To show sex effects, subjects were grouped using sex and age intervals whose boundaries are the average menarche and menopause ages. For each sex and age group, the following SS parameters are shown: (e) Mean duration. (f) Mean PP amplitude. (g) Mean spindle frequency. (h) Spindle density. Women show a greater value than men (p < 0.001, indicated by the symbol ***) in every comparison, except for PP amplitude in 5–12 years old (non-significant difference of + 0.6 μV, p = 0.29). Black circles at the median indicate data with non-normal distribution. See Methods/Statistics for details on the statistical tests.
