Baseline body weight at the beginning and termination of 14-days room air (RA) exposure or 14-days chronic intermittent hypoxia (CIH) exposure in rats.

	Body weight (g)
	RA for 14 days			CIH for 14 days
	N	At beginning	At termination	N	At beginning	At termination
No treatment	24	343.5 ± 11.7	390.8 ± 17.6	24	339.5 ± 13.2	372.1 ± 16.8
Mn treatment	10	335.7 ± 13.6	389.0 ± 19.6	20	340.6 ± 15.3	379.5 ± 17.4
Apo treatment	10	338.1 ± 12.8	394.0 ± 18.4	24	330.4 ± 14.1	375.4 ± 16.5
Veh treatment	10	336.5 ± 14.1	391.5 ± 20.6	20	329.3 ± 15.9	370.8 ± 18.3

Body weights were measured at the beginning of exposure and at the termination of exposure. Rats were exposed to 14-days RA or 14-days CIH with or without daily treatment with MnTMPyP (Mn treatment), apocynin (Apo treatment) or their vehicle (Veh treatment). Data in each group are the means ± SE. N, animal numbers. There was no significant difference (P > 0.05) in mean body weight between the 14-days RA rats and the 14-days CIH rats with or without daily drug treatments either at the beginning of exposure or at the termination of exposure.
