Within-subjects correlations to all sleep stages

Sleep stage in %	Correlation with % memory retention difference
N1	r(147) = –0.056, p = 0.498, BF01 = 12.26
N2	r(149) = 0.109, p = 0.183, BF01 = 6.41
SWS	r(149) = –0.23, p = 0.780, BF01 = 14.91
REM	r(147) = –0.075, p = 0.365, BF01 = 10.22
WASO	r(147) = 0.016, p = 0.848, BF01 = 15.12
TST (in minutes)	r(146) = –0.003, p = 0.968, BF01 = 15.34

Note. The table completes the results for within-subject correlations between the difference in each sleep stage in percent between the intervention and non-intervention condition and the difference in percentage of memory retention across the both naps. BF < 10: moderate evidence for H0, BF > 10: strong evidence for H0.
