Differences in the sMSE indicator before and after the sleep experiment.

	Group 1			Group 2
	Before sleep	After sleep	𝑃 value	Before sleep	After sleep	𝑃 value
sMSE1	1.89 ± 0.07	1.69 ± 0.07	0.017	1.61 ± 0.08	1.76 ± 0.07	0.002
sMSE2	1.88 ± 0.07	1.76 ± 0.07	0.158	1.70 ± 0.06	1.89 ± 0.08	0.013
sMSE3	1.71 ± 0.07	1.63 ± 0.06	0.115	1.65 ± 0.06	1.73 ± 0.06	0.039

Data are expressed as mean ± SE. Variables were compared by using Wilcoxon test, with a 𝑃<0.05 showing statistical significance.
sMSE₁: Sample entropy for each of the coarse-grained time series can be obtained and plotted against the scale factor 1.
sMSE₂: Sample entropy for each of the coarse-grained time series can be obtained and plotted against the scale factor 2.
sMSE₃: Sample entropy for each of the coarse-grained time series can be obtained and plotted against the scale factor 3.
