Multivariate logistic regressions modeling the probability of having carotid artery plaques at baseline (left side) and of developing new carotid artery plaques at three-year follow-up (right side).

	Carotid artery plaques at baseline (n° 1168)		New carotid artery plaques at follow-up (n° 486)
	LR chi² = 355.98; Prob > chi² = 0.0000; Pseudo r² = 0.2352		LR chi² = 226.85; Prob > chi² = 0.0000; Pseudo r² = 0.3468.

^(*)

Variables not entered into the model due to the lack of association with the outcome after age- and sex-adjustment.

^(†)

Variables log-transformed before being entered into regressions due to marked skewness.
