Final model of multiple logistic regression (Breastfeeding excluded) of factors associated with CMV seroprevalence in children 3-5 years of age in the USA.

Table 5: Final model of multiple logistic regression (Breastfeeding excluded) of factors associated with CMV seroprevalence in children 3-5 years of age in the USA.

Variable	Adjusted OR (95% CI)	P Value
Birthweight in gm (less 1500 vs 1500+)	3.92 (0.26-60.43)	0.312
Age of child in years (4-5 vs 3)	1.90 (1.01-3.57)	0.046
Race (non-White vs White)	1.54 (0.96-2.45)	0.070
Cotinine Levels in ng/mL (0.05 vs 0.05+)	0.59 (0.0.38-0.92)	0.022

In this model, when we excluded breastfeeding, cotinine levels were now clearly negatively correlated with CMV seroprevalence.
