Table 2. Linear Regression Analysis of the Association Between Carotid Artery Intima-Media Thickness and Signs of Oral Infections.

Independent Variable	Dependent Variable: Mean IMT in 2007^a
Independent Variable	Standardized β	P Value	R²
Signs of periodontal disease^b	0.137	.01	0.018
Signs of caries^c	0.145	.008	0.022
Signs of oral infections^d	0.158	.004	0.024

Abbreviation: IMT, intima-media thickness.

^{^a}

Multiple linear regression adjusted for the cumulative exposure to cardiovascular disease risk factors during follow-up classified with the area-under-the-curve method. The models were weighed by using inverse probability score. R² values are reported from corresponding unadjusted simple linear regressions with fitting models.

^{^b}

Number of sites with signs of periodontal disease (bleeding on probing and increased probing pocket depth).

^{^c}

Sum of standardized values for number of surfaces with caries and teeth with fillings.

^{^d}

Number of signs of oral infections (bleeding on probing, increased probing pocket depth, caries, and fillings).
