Comparisons between treatment (NMX vs. HPX) in males and females were made using two-way ANOVA with statistical significance (*P < 0.05) indicated by an asterisk to indicate difference from its respective NMX control. EO-HPX, early-onset hypoxia; FBr, fetal brain; FBW, fetal body weight; FHt, fetal heart; FKid, fetal kidney; FLiv, fetal liver; NMX, normoxia; plac, placenta; Wt, weight.
