TABLE 3.

Comparison of amplitude of aEEG in the two groups (mean, μV).

Items	Cases	aEEG before therapy		aEEG after 72-h therapy		t	p
		Maximum voltage	Minimum voltage	Maximum voltage	Minimum voltage
Therapeutic hypothermia group	36	18.6 ± 2.5	6.5 ± 1.9	30.6 ± 2.8ab	13.3 ± 2.2ab	8.951	0.0000
Conventional therapy group	25	22.4 ± 3.1	8.2 ± 2.6	24.1 ± 3.2	9.7 ± 3.4	0.683	0.4975
t		1.264	0.852	6.376	4.257
p		0.2111	0.3976	0.0001	0.0001

Compared with the conventional therapy group, ^ap < 0.05; compared with the aEEG recording before therapy, ^bp < 0.05.
