CAP rate during stage N2 and N3 of NREM sleep in the three groups.

Features	Group	Values (Mean +/– SD)	P-value	post-hoc	Effect size
CAP rate SWS (%)	HC DoA SHE	30 +/– 8 65,9 +/– 17,3 76 +/−24	p < 0.001	HC vs. DoA: p = 0.000 HC vs. SHE: p =0.000 DoA vs. SHE: p = 0.0792	Overall effect size Cohen's f = 10,607
					HC vs. DoA: f = 0.7624 HC vs. SHE: f = 1.0440 DoA vs. SHE: f = 0.2427
					F(2, 90) = 45.618 eta squared = 0.503
CAP rate N2 (%)	HC DoA SHE	34 +/– 6 50,1 +/– 14,7 55 +/– 14	p < 0.001	HC vs. DoA: p = 0.000 HC vs. SHE: p = 0.000 DoA vs. SHE: p = 0.2588	Overall effect size Cohen's f = 0.6993
					HC vs. DoA: f = 0.4951 HC vs. SHE: f = 0.6902 DoA vs. SHE: f = 0.1705
					F(2, 90) = 21.045 eta squared = 0.319

DoA, disorder of arousal; SHE, sleep-related hypermotor epilepsy; HC, healthy controls; SWS, slow wave sleep. Significant results are marked in bold P-values from one-way Anova with Tukey HSD post-hoc test. Effect size: according to Jacob Cohen f values of 0.10, 0.25, and 0.40 represent small, medium, and large effect sizes, respectively; partial eta squared is a measure of the proportion of the total variance in a dependent variable that is associated with the membership to different groups. Values of eta-squared of 0.01, 0.06, and 0.14 represent small, medium, and large effect sizes, respectively.
