MTHFR C677T: wild type (C/C), heterozygote (C/T) and homozygote (T/T); MTHFR A1268C: wild type (A/A), heterozygote (A/C), homozygote (C/C); MTR A2756G: wild type (A/A), heterozygote (A/G), homozygote (G/G). Data show the number of control and preeclamptic patients with or without the polymorphism. Statistical significance was assessed using Fisher's exact test.
