Comparison of mean age and weight of animals used to obtain carotid bodies for ex vivo recordings between the different experimental groups.

	Males		Females		Treatment effect	Sex effect	Factorial interaction
	Control (n = 8)	NMS (n = 8)	Control (n = 5)	NMS (n = 5)
Age (days)	66 ± 10.6	66 ± 8.6	55 ± 3.6†	57 ± 4.4	P = 0.67	P = 0.007	P = 0.72
Weight (g)	459 ± 54	431 ± 108	219 ± 22†	298 ± 51†	P = 0.41	P < 0.0001	P = 0.09

Data are reported as means ± SD.

^†Indicates a value statistically different from corresponding male value at P < 0.05. Bold indicates a significant factoral effect.
