A Crossover Comparison of the Sensitivity and the Specificity between BIS and AEP in Predicting Unconsciousness in General Anesthesia

Table 9

Correlation of depth of anesthesia (4 stages, including baseline) vs. BIS and AEP.

	Spearman correlation coefficient, r [95% CI]		value (: ssevo = sprop)
	Propofol	Sevoflurane
BIS	−0.92 [−0.87, −0.95]	−0.86 [−0.79, −0.91]	<0.05
AEP	−0.80 [−0.71, −0.87]	−0.61 [−0.45, −0.73]	<0.05
value (: sBIS = sAEP)	<0.05^∗∗	<0.05^∗∗

Standard errors (SE) for the above s are 0.11. Significantly different from s = 0 at 0.05.
