Table 3 Comparison of two groups of lung function indicators (mean ± SD)

Pulmonary function indicators	Phase	Control group (n = 77)	Observation group (n = 77)	t value	P value
FEV₁ (L)	Before intervention	1.24 ± 0.19	1.21 ± 0.22	0.906	0.367
FEV₁ (L)	Postintervention	1.62 ± 0.27^a	1.98 ± 0.39^a	6.660	< 0.001
FVC (L)	Before intervention	1.93 ± 0.31	1.91 ± 0.34	0.381	0.703
FVC (L)	Postintervention	2.41 ± 0.39^a	2.86 ± 0.45^a	6.631	< 0.001
FEV₁/FVC (%)	Before intervention	64.52 ± 4.56	63.35 ± 5.32	1.460	0.146
FEV₁/FVC (%)	Postintervention	67.22 ± 4.26^a	69.23 ± 6.05^a	2.384	0.018

^aP < 0.05 vs before intra group intervention.
