4 February 2008	Amended	Converted to new review format.
26 October 2007	New citation required and conclusions have changed	The conclusions have changed: the evidence from this review does not support routine antioxidant supplementation during pregnancy to reduce the risk of pre‐eclampsia and other serious complications in pregnancy.
26 October 2007	New search has been performed	Search updated in May 2007. We identified 15 new trials. Four have been included (Mahdy 2004; Merchant 2005; Poston 2006; Rumbold 2006); three are awaiting assessment (Kubik 2004; Negro 2007; Rumiris 2006) and eight have been excluded (Borna 2005; Casanueva 2005; Dijkhuizen 2004; Radhika 2003; Roes 2006; Theobald 1937; Thomson 2001; West 1999). We moved one study from the included to the excluded studies (People's League 1942) because we now exclude quasi‐random studies ‐ see differences between protocol and review.
