Hazard ratios for chronic heart failure are linked to placental size and maternal weight

	Mother's Height, cm
Placental Area, cm2	<160	>160
−225	2.3 (1.2–4.2)	1.2 (0.6-2.4)
−255	1.1 (0.6–2.2)	0.9 (0.5–1.9)
−295	1.8 (0.9–3.3)	1.1 (0.6–2.1)
>295	1.0 (baseline)	1.0 (baseline)
P value	0.05	0.5

Confidence intervals are given in parentheses. Data from Barker et al. (27).
