Demographic details of samples used for experimental comparisons. The left hand columns relate to samples obtained from cases of FGR that were live or stillborn; all these samples had a birthweight <5th centile. The right hand columns relate to samples used for perfusion experiments. Data are presented as median with range in parentheses
