The relationship between the SNRs and alterations in the four topological properties between the two types of networks at 12, 15, 20, and 30 Hz, respectively.

Frequency (Hz)	Clustering coefficient		Characteristic path		Global efficiency		Local efficiency
	r	p	r	p	r	p	r	p
12	0.56	0.007	−0.64	0.002	0.56	0.007	0.56	0.008
15	0.64	0.002	−0.66	0.001	0.65	0.001	0.65	0.001
20	0.88	<0.001	−0.83	<0.001	0.89	<0.001	0.89	<0.001
30	0.71	<0.001	−0.64	0.002	0.71	<0.001	0.71	<0.001

r denotes correlation coefficients, and p denotes the significance level of the correlation coefficients.
