Comparison of Sleep and Stress at T0 and T1 between starting group with music at 432 Hz and starting group with music at 440 Hz (6 patients per group) during first listening period

Times	Variables	432 Hz	440 Hz
T0	Average of the hours slept each night	7.33 (SD±0.81)	4.67 (SD±1.96)
	Average of the sleep total scores	36 (SD±7.92)	33 (SD±4.47)
	Average of the stress total scores (PSS)	14 (SD±11.36)	23.17 (SD±7.38)
T1	Average of the hours slept each night	7.17 (SD±0,98)	5 (SD±1.78)
	Average of the sleep total scores	43 (SD±6.35)	30.83 (SD±7.41)
	Average of the stress total scores (PSS)	9.67 (SD±7.06)	20.67 (SD±9.33)
T Test Differences T0-T1 (p value)	Average of the hours slept each night	-0.16 (p=0.61) ns	0.33 (p=0.17) ns
	Average of the sleep total scores	7 (p=0.05) *	-2.17 (p=0.38) ns
	Average of the stress total scores (PSS)	-4.33 (p=0.26) ns	-2.50 (p=0.49) ns

Legend: *=p value<0.05; **=p value<0.01; ***=p value<0.001; ns = not significant
