Comparison of pulmonary function between the two groups

Pulmonary unction index	Pre-treatment		t	P value	Post-treatment		t	P value
Pulmonary unction index	Observation group (n = 65)	Control group (n = 65)	t	P value	Observation group (n = 65)	Control group (n = 65)	t	P value
MVV (L/min)	4.26 ± 0.22	4.32 ± 0.63	1.956	0.643	7.36 ± 1.54^a	5.97 ± 1.47	4.278	0.003
FEV1 (L)	1.16 ± 0.21	1.28 ± 0.66	1.537	0.291	3.43 ± 1.25^a	1.89 ± 0.98	2.089	0.014
FEV1/FVC (%)	64.6 ± 5.34	65.4 ± 4.65	0.958	0.452	79.8 ± 5.56^a	73.8 ± 5.06	2.563	0.013
PEF (L/s)	2.23 ± 0.56	2.08 ± 0.58	1.071	0.749	3.56 ± 0.78^a	3.05 ± 0.54	2.417	0.021

^a

P < 0.05 vs before and after intervention in the same group.

MVV: Maximal voluntary ventilation; FEV1: Forced expiratory volume in one second; FVC: Forced vital capacity; PEF: Peak expiratory flow.
