Table 3:

Final model of CTA markers associated with IPH^{^a}

Carotid IPH Prediction	PR	P Value	95% CI
Carotid plaque rim sign (present versus absent)	11.9	<.001	4.4–32.0
Maximum soft-plaque thickness (per 1-mm increase)	1.2	.06	0.99–1.40

Note:—PR indicates prevalence ratio.
↵a After multivariable Poisson regression with sequential backward elimination of factors that did not meet the threshold of P < .10, the final carotid IPH model depended on the positive rim sign and maximum soft-plaque thickness.
