Cross‐tabulated results of thoracic auscultation (AUSC) and thoracic ultrasounds exam (TUS) on 330 dairy calves for diagnosing bronchopneumonia.

|---|---|---|---|---|---|---|
| TUS (0‐3) | 0 | 1 | 2 | 3 | 4 | Total |
| 0 | 25 (7.6%) | 1 (0.3%) | 14 (4.2%) | 0 (0%) | 0 (0%) | 40 (12.1%) |

Note: Systematic TUS (intercostal spaces [ICS] 10‐1 on the right and ICS 10‐2 on the left) score ranged between 0 to 3 (0 = no lesions; 1 = diffuse comet tails; 2 = patchy lesions; consolidation of ≥1 cm but <3 cm, between a normal aired lung parenchyma; 3 = lung consolidated area ≥ 3 cm). Thoracic auscultation scoring system ranged from 0 to 4 (0 = normal breath sounds; 1 = increased breath sounds; 2 = wheezes or crackles in at least 1 auscultation site; 3 = increased bronchial sounds; 4 = pleural friction rubs).
