Data are means ± SEM. Whole blood measures of partial pressure of carbon dioxide (, mmHg; A); partial pressure of oxygen (, mmHg; B); pH (C); glucose (mmol·L−1; D); and) lactate (mmol·L−1; E) in FGRS (grey, n = 20–34) and FGRI (black, n = 20–32) fetuses; and the correlation between mean maternal N‐terminal pro‐C‐type natriuretic peptide (NTproCNP, pmol·L−1) during the embolisation period (103–107 dGA) and fetal in growth‐restricted FGR (white, n = 2), FGRS (grey, n = 7), and FGRI (black, n = 7) fetuses (F). Symbols denote significant differences over time (RM ANOVA: i, P < 0.05).
