Demographic and Clinicopathological Characteristics of the Participants
| Group | HPH (n=3) | Normal (n=3) | P value |
|---|---|---|---|
| Age | 77.00±2.65 | 73.67±7.57 | 0.51 |
| FEV1/pred, % | 51.70±2.87 | 91.83±1.79 | <0.001 |
| FEV1/FVC, % | 48.90±2.62 | 84.97±2.12 | <0.001 |
| mPAP, mm Hg | 59.67±13.87 | 17.33±2.08 | <0.001 |
Mean±SD. P<0.05 is considered to be significant. FEV1 indicates forced expiratory volume in 1 s; FEV1/pred, forced expiratory volume in 1 s as percentage of predicted value; FVC, forced vital capacity; HPH, hypoxia‐induced pulmonary hypertension; and mPAP, mean pulmonary artery pressure.
