Figure 2.
Comparison of lung function between the two groups. Before treatment, there was no significant difference in lung function between the two groups (P>0.05). After treatment, the lung function indexes MVV, PEF, FEV1, FEV1/FVC% were significantly higher than those before treatment (P <0.05). MVV, PEF, FEV1, FEV1/FVC% in the study group were significantly higher than those in the control group, with statistically significant differences (P<0.05). a vs. before treatment, aP<0.05; b vs. the study group after treatment, bP<0.05.
