Table 2

Comparison of pulmonary function tester parameters before and after treatment.

Group	FVC (L)		FEV1 (L)		FEV1/FVC (%)
	Before 12 weeks	After 12 weeks	Before 12 weeks	After 12 weeks	Before 12 weeks	After 12 weeks
Experimental group	1.9 ± 0.1	3.3 ± 0.1^∗^#	1.5 ± 0.2	2.6 ± 0.2^∗^#	62.3 ± 8.3	74.9 ± 8.7^∗^#

^#Compared with the control group,  < 0.05. ^∗Compared with 12 weeks before,  < 0.05. FVC, forced vital capacity; FEV, forced expiratory volume in the first second.
