| SpO2 level/RR | Group A (n = 99) | Group B (n = 182) | Group C (n = 412) | Differences group A–B (p values) | Differences group B–C (p values) |
|---|---|---|---|---|---|
| SpO2 (%) day 0 | 92.1 (1.4) | 90.8 (1.6) | 94.8 (1.2) | <0.0001* | <0.0001* |
| SpO2 (%) day 1 | 94.3 (1.2) | 90.6 (1.3) | 96.6 (1.3) | <0.0001* | <0.0001* |
| SpO2 (%) day 2 | 96.6 (1.1) | 94.8 (1.4) | 98.4 (1.5) | <0.0001* | <0.0001* |
| RR (breaths/min) on day 0 | 15.8 (1.9) | 12.4 (2.4) | 16.1 (0.9) | <0.0001* | <0.0001* |
| RR (breaths/min) day 1 | 16.6 (1.4) | 13.6 (2.9) | 18.0 (0.7) | <0.0001* | <0.0001* |
