Figure 1From: Endothelial nitric oxide synthase gene polymorphism (Glu298Asp) and development of pre-eclampsia: a case-control study and a meta-analysisResults of published studies of the association between the eNOS Glu298Asp polymorphism and pre-eclampsia. ORs for the outcome compared homozygous women for the Asp298 allele vs heterozygous (Glu/Asp) plus wild type (Glu/Glu) women (Recessive model), sorted by study size.Back to article page
