Data are reported as n (%), mean ± standard deviation, or median (first quartile, third quartile) with p values calculated using chi-square or Fisher’s exact test for categorical variables, t test for normal numeric variables, and Wilcoxon rank sum test for non-normal numeric variables. IUFD, intrauterine fetal demise; BMI, body mass index; GA, gestational age.
Includes uterine fibroids; inflammatory bowel disease with blood in stool at time of presentation; venous thrombosis; pulmonary embolism; stroke; sickle cell trait; chronic idiopathic thrombocytopenia; and anemia, abnormal uterine bleeding, and obstetric hemorrhage requiring transfusion or hospitalization.
For descriptive use only; no tests of association performed for race or ethnicity.
