Data are presented as n/N (%) or mean ± standard deviation (n) [median] (range)
^aAble to navigate successfully and allow a tissue biopsy (according to subjective operator assessment)
^bMore than one tool used per procedure
^cPer subject, among subjects with an ENB-aided tissue sample obtained. Data missing for 1 subject
^dPer lesion, among 247 lesions with primary adenocarcinoma (n = 233) or primary non-small-cell lung cancer not otherwise specified (n = 14). More than one reason could be chosen per lesion
