We have also observed that the incidence of NTD in Asturias remained constant in the last six years, around 1.5\u20101.6 per 1000 pregnancies. However, due to MSAFP screening, there has been a decline in the prevalence of children born with these defects. We conclude that MSAFP screening is the best tool to identify and reduce NTD in our Region (Spain).<\/jats:p>","DOI":"10.3109\/00016349509024447","type":"journal-article","created":{"date-parts":[[2007,11,22]],"date-time":"2007-11-22T00:47:05Z","timestamp":1195692425000},"page":"266-269","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Maternal serum alpha\u2010fetoprotein screening for neural tube defects"],"prefix":"10.1111","volume":"74","author":[{"given":"M.","family":"Candenas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Villa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
