P values were omitted in 2 places in a table in an original research article.

Table 2, “Sociodemographic and clinical characteristics of women delivered by the hospitalist group versus the private practice group,” appears on page 491.e4. Under column 1, “Characteristics,” the first category is “Sociodemographic characteristics.” Findings in the third subcategory, “High school graduate or less,” were given no P value; it is <.001.

The last category under “Characteristics” is “Infant characteristics.” For the first subcategory, “Birthweight ≥4000 grams,” the P value is also <.001.

In each case the P value pertains to both the hospitalist group and the private practice group.
