Table 5. Final regression models for common carotid intimal media thickness in European-Americans.

Independent Variable (increment)	CC IMT (n = 396)
	β-Coefficient (95% CI)
Age (10 yr. increase)	0.11 (0.09, 0.13)
BMI (5.6 kg/m²)	0.03 (0.01, 0.04)
CD4⁺ Memory cells (15.2%)	0.02 (0.006, 0.04)
CD4⁺ Naive cells (14.2%)	−0.02 (−0.004, −0.03,)
Model R²	0.36

Multivariate regression was performed as described in Methods with common carotid intimal media thickness (CC IMT) as the dependent variable. CD4⁺ naive and memory cells were analyzed in separate models. Analyses were stratified by race/ethnicity; results from European-Americans are presented.
