实验组康复训练前后的比较
Comparative analysis before and after intervention
| Before the exercise | After the exercise | P value | |
| *Higher scores indicate better functioning (scaled from 0-100); †Lower scores indicate less dyspnea (scaled from 0-100). PEF: peak expiratory flow; PO2: partial pressure of oxygen; PCO2: partial pressure of carbon dioxide; SaO2: arterial oxygen saturation; QoL: quality of life. | |||
