Clinical signs (mean) in groups of brachycephalic obstructive airway syndrome patients before and after surgery
| Respiratory signs | Gastrointestinal signs | Exercise intolerance | Sleep disorders | |
|---|---|---|---|---|
| Grade 1 | ||||
| Before surgery | 3.1 | 1.8 | 2.1 | 3.7 |
| After surgery | 1.5 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
1.2 | 1.0 | 2.0 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
| Grade 2 | ||||
| Before surgery | 3.2 | 2.3 | 1.8 | 4.1 |
| After surgery | 1.8 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
1.6 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
1.5 | 2.4 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
| Grade 3 | ||||
| Before surgery | 3.1 | 2.1 | 1.8 | 3.8 |
| After surgery | 1.9 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
1.4 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
1.2 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
2.7 Significant (P < 0.05) difference in comparison to values before surgery 1.0 means that the clinical sign was not present and 5.0 means that the clinical sign was always present |
