Note: abbreviations: TBB = transbronchial biopsy; TBLC = transbronchial lung cryobiopsy; EBUS = endobronchial ultrasonography; EBUS + = nodule visualization by EBUS miniprobe. EBUS - = no nodule visualization by EBUS miniprobe. Bronchus sign + = presence of a bronchus sign. Bronchus sign - = absence of bronchus sign.
