Mean (SD) demographic characteristics of the patient populations
| Age (years) | M/F (%) | FEV1(l) | KPI | |
|---|---|---|---|---|
| COPD | 70.5 (5.5) | 44/56 | 0.52 (0.17) (n=49) | 62.5 (10.4) |
| NSCLC | 71.4 (6.5) | 72/28 | 1.47 (0.39) (n=42) | 66.9 (9.2) |

Forced expiratory volume in one second (FEV1) and Karnofsky Performance Index (KPI) were used to help define the groups.
KPI scale 0–100: a score of 50–80 indicates severe disability with a lower score indicating worsening performance.
