  1. Combined tests in the group include common bronchoscopy, fine bronchoscopy, therapeutic bronchoscopy, EBUS-TBNA, guided bronchoscopy, TTCB and CNB, among others. The guiding techniques include radial endobronchial ultrasound, virtual bronchoscopy navigation and fluoroscopy in guided bronchoscopy.
  2. p1 was obtained by comparing optimal and total diagnostic yields within a group.
  3. p2 was obtained by comparing optimal or total diagnostic yields between two groups.
  4. Significant values are in italic.
