Table 5. Comparison of Fontaine class, ultrasonic score, and number of lower extremity occluded segments between subgroups based on the presence/absence of internal carotid artery plaques.

Variable	No plaques (n=86)	With plaques (n=81)	P value
Fontaine class	1 (1−5)	4 (1−5)	<0.001
Ultrasonic score	7 (7−17)	12 (7−16)	<0.001
Number of lower extremity occluded arterial segments	0 (0−5)	2 (0−4)	<0.001

Data are reported as median (range). Mann-Whitney test was used for analyses.
