Increased N1 sleep-related EEG signatures during deep sleep related periods in ID.

	Controls	ID	Δ	P
Co-occurrence of T2 [%]	33.48 (23.47–43.50)	21.15 (11.80–30.50)	-12.58 (-26.75–1.58)	0.10
Co-occurrence of T3 [%]	9.06 (5.60–12.52)	8.17 (5.62–10.72)	-0.81 (-5.33–3.70)	0.71
Co-occurrence of T4 [%]	4.49 (2.70-6.29)	8.44 (5.43-11.46)	4.12 (0.79–7.44)	0.02
Co-occurrence of T5 [%]	7.83 (4.63–11.03)	8.13 (5.39–10.86)	0.56 (-3.84–4.95)	0.84
Co-occurrence of T6 [%]	45.08 (36.71–53.46)	53.59 (43.57–63.62)	8.69 (-4.32–21.70)	0.20

The normalized co-occurrence of topics T2-T6 in periods where the deep sleep-related topic T1 is dominant and stable. The values are reported as estimates, their 95th confidence intervals, and P-values obtained from linear mixed effect models with group, age and sex as fixed-effect factors, and a random intercept for each subject. Bold font-style indicates significant group differences.
