Identification of Cerebral Artery Stenosis Using Bilateral Photoplethysmography

Table 2

Sensitivity and specificity for the proposed technique in the best recognition rate.

	Feature type	Performance parameters
		Sensitivity (true positive)	Specificity (true negative)
Proposed technique	MPA	90.6%	93.8%
	MNA	80%	100%

MPA: maximum positive amplitude; MNA: maximum negative amplitude.
