Inclusion criteria
Inclusion criteria: 1. Consecutive adult patients (aged >18 years) who underwent diagnostic bronchoscopy for pulmonary lesions during the study period were eligible for inclusion. 2. Eligible cases included procedures performed with the intent to obtain a pathological diagnosis using either conventional flexible bronchoscopy or radial endobronchial ultrasonography (R EBUS) guided bronchoscopy under fluoroscopic guidance. 3. Patients with pathological results and clinical or radiological follow-up were not used as exclusion criteria. 4. Patients with non-diagnostic bronchoscopic findings were retained in the analysis.
Exclusion criteria
Exclusion criteria: 1. Patients whose bronchoscopy was performed for non-diagnostic indications. 2. Patients whose the target lesion was endobronchially visible during bronchoscopy, or if no bronchoscopic sampling was attempted. 3. Patients with incomplete diagnostic data or follow-up data.
