Flow diagram depicting how patients were selected for study inclusion. PPL = parenchymal pulmonary lesion; ENB = electromagnetic navigation bronchoscopy; RAB = robotic-assisted bronchoscopy. In patients with “bronchus sign” present, the presence of the “artery sign” was not evaluated since the planning software and algorithm are based on airway segmentation, and therefore the presence of the “artery sign” does not impact the workflow of the procedure.
