| Variable | Follow-up 1 Mean (SD) | Follow-up 2 Mean (SD) | p-value |
|---|---|---|---|
| SpO2 initial (%) | 96.21(1.46) | 95.81 (1.60) | 0.652 |
| SpO2 final (%) | 93.03 (4.35) | 90.44 (5.96) | 0.681 |
| HR initial (bpm) | 80.53 (16.73) | 80.38 (14.07) | 0.103 |
| HR final (bpm) | 115.95 (16.62) | 122.88 (14.96) | 0.948 |
| RR initial (brpm) | 18.0 (3.04) | 17.25 (3.49) | 0.222 |
| RR final (brpm) | 26.49 (4.86) | 24.73 (3.31) | 0.254 |
| 6MWTD, m | 498.3 m (114.4) | 494.0 (94.4) | 0.999 |
| 6MWTD, % | 85.7 (21.2) | 86.7 (18.2) | 0.470 |
SD = standard deviation; SpO2 = saturation by pulse oximetry; HR = heart rate; RR = respiratory rate; brpm = breaths per minute; 6MWTD = 6-min walk test distance; bpm = beats per minute; 6MWTD % = 6-min walk test distance in predicted percentage.
