^aBAL = bronchoalveolar lavage; TBCB = transbronchial cryobiopsy; TBFB = transbronchial forceps biopsy.

^bData are presented as No. (percentage).

^cChi-square test.

^dSignificant bleeding was defined as the need for blood products (n=0) or change in procedure protocol to control excessive bleeding (eg, prolonged tamponade).

^eEscalation of care was defined as the change in disposition (hospitalization/intensive care unit admission) or increase in ventilator/oxygen requirements upon discharge from the postprocedural recovery unit.
