Body and heart weights of fetal sheep in the aortic constriction model

	Gestational age (days)	Body weight (kg)	Heart weight (g)	Heart/fetal weight ratio (g/kg)
Control	134.8 ± 0.4	4.8 ± 0.9	31.4 ± 7.6	6.5 ± 0.6
Aortic constriction	134.6 ± 0.5	4.4 ± 0.9 (P = 0.458)	33.9 ± 8.7 (P = 0.611)	7.7 ± 0.7 (P = 0.012)

Data are presented as means ± SD, with P-values as indicated. Statistical comparisons were made vs. control using unpaired t tests. n animals = 6 for the control group and 5 for the aortic constriction group.
