title: Possible prevention of neural-tube defects by periconceptional vitamin supplementation.
abstract: Women who had previously given birth to one or more infants with a neural-tube defect (NTD) were recruited into a trial of periconceptional multivitamin supplementation. 1 of 178 infants/fetuses of fully supplemented mothers (0.6%) had an NTD, compared with 13 of 260 infants/fetuses of unsupplemented mothers (5.0%).
