Table 4. Comparison of internal carotid artery plaque prevalence, Fontaine class, ultrasonic score, and number of lower extremity occluded segments between subgroups based on carotid intima-media thickness (CIMT).
| Variable | CIMT <0.71 mm (n=56) | CIMT ≥0.71 mm (n=111) | P value |
|---|---|---|---|
| Internal carotid artery plaques | |||
| No | 39 (69.64%) | 47 (42.34%) | 0.001 |
| Yes | 17 (30.36%) | 64 (57.66%) | 0.001 |
| Fontaine class | 1 (1−5) | 3 (1−5) | <0.001 |
| Ultrasonic score | 7 (7−16) | 11 (7−17) | <0.001 |
| Number of lower extremity occluded arterial segments | 0 (0−4) | 1 (0−5) | <0.001 |
Data are reported as median (range) or number (percentage). χ 2 test and Mann-Whitney test were used for analyses.
