Table 2.
Comparison of pulmonary function between the 2 groups of patients before and after discharge
| Intervention time | FEV1% predictive value | FEV1/FVC | |
|---|---|---|---|
| Intervention group (n = 120) | Discharge | 40.98±9.86 | 54.08±6.38 |
| One year after discharge | 62.94±10.12a | 65.36±5.85a | |
| p value | 0.012 | 0.013 | |
| Control group (n = 120) | Discharge | 41.08±9.27 | 53.47±6.62 |
| One year after discharge | 47.87±4.68a | 59.71±4.28a | |
| p value | 0.024 | 0.027 | |
FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity.a Compared with the same group at discharge (p < 0.05); the FEV1% and FEV1/FVC of the 2 groups were improved after 1 year of follow-up (p < 0.05).
