Table 2.

Demonstrates the detection ratio in each subgroup. Logistic regression analysis demonstrates the significant influence of seizure frequency on the detection ratio

variable	subgroup	number of patients	detection ratio
gender	male	152	57.9
	female	99	56.6
use of anti-seizure medication	subgroup M0	40	67.5
	subgroup M1	93	49.5
	subgroup M2	118	60.2
interval time#	≤ 24 h	82	73.2
	24 h-7d	74	54.1
	> 7d	95	46.3
seizure frequency**	subgroup F1	62	85.5
	subgroup F2	43	72.1
	subgroup F3	92	46.7
	subgroup F4	54	31.5

**P < 0.001. The differences in detection ratio among the various interval time subgroups are significant by the chi-square test (#P = 0.001)
