Data were expressed as mean ± standard deviation or as numbers and percentages. * was statistically significant compared with Group Non-acute
Location I: hemorrhage lesions were located in the main airway; Location II: hemorrhage lesions were located in the left/right mainstem bronchus; Location III: hemorrhage lesions were located both in the main airway and mainstem bronchus
Group Acute: bronchoscope-related acute massive airway hemorrhage group; Group Non-acute: bronchoscope-related non-acute massive airway hemorrhage group
