W (% of TIB)	µ ± σ	18.80 ± 12.05	18.95 ± 12.39	24.57 ± 15.01	n.s.	< .001	< .001
	m [5th–95th]	16.49 [4.40–42.49]	16.62 [4.13–42.58]	21.71 [6.61–53.8]
N1 (% TIB)	µ ± σ	11.44 ± 6.61	20.43 ± 10.12	4.49 ± 3.05	< .001	< .001	< .001
	m [5th–95th]	9.88 [4.48–23.86]	18.55 [7.54–39.83]	3.76 [0.89–10.02]
N2 (% TIB)	µ ± σ	40.85 ± 9.47	31.41 ± 10.67	47.68 ± 11.44	< .001	< .001	< .001

N3 (% TIB)	µ ± σ	10.92 ± 7.01	14.71 ± 7.23	6.10 ± 6.23	< .001	< .001	< .001
	m [5th–95th]	10.85 [0.00–22.99]	14.29 [3.19–26.94]	4.50 [0.00–18.19]
REM (% TIB)	µ ± σ	14.34 ± 5.78	10.86 ± 5.54	11.91 ± 6.13	< .001	< .001	.001

The distributions are calculated as percentage of time in bed (TIB) and shown as mean (µ) ± 1 standard deviation (σ), median (m), and 5th–95th percentiles across the participants. Statistical analyses were performed with Mann-Whitney U tests corrected with Bonferroni procedure. Statistical significance was set at the value of .05. AUTO = automatic algorithm, BER = Berlin, INN = Innsbruck, N1 = non-REM stage 1 sleep, N2 = non-REM stage 2 sleep, N3 = non-REM stage 3 sleep, n.s. = nonsignificant; REM = rapid eye movement, W = wakefulness.
