title: WITHDRAWN: Vitamin D supplementation in pregnancy.
abstract: BACKGROUND
  Vitamin D deficiency can occur in people whose diet is relatively low in the vitamin and those who are not exposed to much sunlight.
  
  
  OBJECTIVE
  The objective of this review was to assess the effects of vitamin D supplementation on pregnancy outcome.
  
  
  METHODS
  We searched the Cochrane Pregnancy and Childbirth Group trials register (October 2001) and the Cochrane Controlled Trials Register (Issue 3, 2001).
  
  
  METHODS
  Acceptably controlled trials of vitamin D supplementation during pregnancy.
  
  
  METHODS
  One reviewer assessed trial quality and extracted data.
  
  
  RESULTS
  Two trials involving 232 women were included. In one trial the mothers had higher mean daily weight gain and lower number of low birthweight infants. In the other trial the supplemented group had lower birthweights.
  
  
  CONCLUSIONS
  There is not enough evidence to evaluate the effects of vitamin D supplementation during pregnancy.
