Serum 25-hydroxyvitamin D and calcium levels

	Vitamin D deficient		Control
	Air-exposed	CS-exposed	Air-exposed	CS-exposed
25OHD (ng/ml)	19.76 ± 1.87a	17.37 ± 2.68b	76.30 ± 3.15	86.76 ± 4.03
Calcium (mg/dl)	9.71 ± 0.62	10.97 ± 0.47	10.24 ± 0.26	9.09 ± 1.21

At the age of 8 weeks, C57Bl/6J vitamin D deficient and control mice were exposed to CS or ambient air for a period of 6 or 12 weeks. Data show results after 12 weeks and are represented as mean ± SEM.^a p < 0.0001 vs air-exposed control;^b p < 0.0001 vs CS-exposed control
