Percentages are based on the number of pregnancies; pregnancies include 266 multiple gestation births (262 twin and four triplet).
P‐value is based on the independent t‐test.
P‐value is based on the Fisher's exact test (chi‐square test for Race). Analysis does not include N/A, Unknown, or Missing values.
