AHA indicates American Heart Association; CBC, complete blood count; CHD, congenital heart defects.
* Chi square P<0.05 from generalized estimating equation approach to logistic regression, accounting for multiple pregnancies per woman; assesses distribution of test/assessment by levels of maternal characteristic (eg, receipt of CBC differentially distributed by maternal age at conception).
†Nineteen pregnancies among women with no information on region of residence.
