Table 4.

The comparison of p-values for 6 participants in frequency domain features (APSD) under two psychological states (healthy controls and bruxsim) for C4P4 channel

SN	Features	healthy controls (mean ± SD) (mV2/Hz)	Bruxsim (mean ± SD) (mV2/Hz)	p-value
1	APSD(δ)	83.048 ± 16.083	129.720 ± 65.344	<=0.001**
2	APSD(θ)	16.698 ± 2.191	17.517 ± 5.569	<=0.001**
3	APSD(α)	3.885 ± 0.111	7.135 ± 2.170	<=0.001**
4	APSD(β)	2.367 ± 0.059	4.292 ± 1.203	0.188

The ‘*’ and ‘**’ represent alpha levels: p = 0.05, and p = 0.001 correspond to significant differences, respectively
