Correlation between a gene hypoxia score and umbilical artery lactate concentrations sampled after labour. Gene hypoxia score is the sum of relative hypoxia inducible factor (Hif)1α, Hif2α, adrenomedullin (Adm) and lactate dehydrogenase A (LdhA) expression in maternal blood taken at the moment of delivery. P <0.0001.
