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

Table 8

Correlation analysis of BIS vs. AEPi in the sevoflurane group.

Sevoflurane		Correlation coefficient, r
		BIS
		Base	Sedation	Unconc	Anes
AEPi	Base	0.66	0.27	0.18	0.14
	Sedation	0.29	0.23	0.17	0.18
	Unconc	0.33	0.26	0.38	0.17
	Anesthesia	0.16	0.12	0.52	0.21

Significant different from r = 0 at the 0.05 level. r = 1 or −1 means perfect correlation. r = 0 means no correlation.
