Body weight, heart weight, and hemodynamic data after exposure to 10% O₂ (hypoxia) or room air

(normoxia)

	Normoxia		Hypoxia
	IL-6+/+ n = 8	IL-6-/- n = 8	IL-6+/+ n = 8	IL-6-/- n = 8
Final body weight (g)	25.2 ± 0.3	22.9 ± 0.5**	24.7 ± 0.6	20.6 ± 0.7**
RV/BW (mg/g)	0.96 ± 0.02	0.85 ± 0.03	1.24 ± 0.07$$$	1.02 ± 0.07*
LV/BW (mg/g)	3.8 ± 0.06	3.7 ± 0.15	3.6 ± 0.1	3.9 ± 0.1
Heart rate (beats/min)	308 ± 21	318 ± 24	327 ± 11	318 ± 23

All values are mean ± SEM.

*P < 0.05 and **P < 0.01 compared with corresponding values in wild type mice.

^$P < 0.05 and ^$$P < 0.01 compared with corresponding values under normoxia.

RV/BW, right ventricular weight/body weight; LV/BW, left ventricular weight/body weight.
