† P values for continuous variable analyses are from the independent sample t test for well-child visits, which are normally distributed, and from the Mann-Whitney U test for ED visits and hospitalizations, which are not normally distributed.
‡ P values for categorical variable analyses are from the Pearson χ2 test.

In this table, only the relative risk for continuity is presented. Each model controlled for the baby's gender, race, county of residence, and the mother's age.
† Count outcome multivariate analyses were performed using negative binomial regression.
‡ Categorical outcome multivariate analyses were performed using logistic regression.
