Neural tube defects (NTDs)—malformations secondary to abnormal neural tube closure
between the third and fourth weeks of gestational age—have a complex and imperfectly …

Using data from the Northern Congenital Abnormality Survey, we describe trends in the
prevalence of neural tube defects (NTDs), maternal age‐specific prevalence, outcome of …

Isolated neural tube defects (NTDs) appear to have different risk factors compared to
nonisolated NTDs. To extend those observations, we explored routinely collected child and …

We previously reported that among neural tube defects (NTDs) with no known causes the
ones that occur alone (singles) have different epidemiologic characteristics from those that …

The epidemiology of neural tube defects was reviewed, using data from two birth defects
surveiliance systems: the nationwide Birth Defects Monitoring Program and the Metropolitan …

The aetiology of neural tube malformations may include both genetic and environmental
elements. The genetic factors considered are:(a) a preponderance of one or other sex;(b) …

Abstract In the NIH Collaborative Perinatal Project, a prospective study of over 53,000

Neural tube defects (NTDs) are a group of malformations of the brain and spinal cord that
originate at various times during gestation. The most common NTDs are anencephaly and …

Study objective-The aims were (1) to determine whether in Europe, 1980-86, geographical
differences in total prevalence of neural tube defects persist;(2) to examine the stability of …

This study presents race/ethnicity-specific prevalence estimates of neural tube defects
(NTDs) in California using 5 years of population-based data. NTD prevalence estimates …
