1. Baseline of patient characteristics and lesion features (N=109).

Characteristics n (%)
CT, computed tomography; EBUS, endobronchial ultrasonography; Within type, the probe was placed in a bronchus that ran inside the lesion; Adjacent type, the probe was placed in a bronchus that ran alongside the lesion; Without type, the probe was placed in a bronchus that far from the lesion or the probe could not access the lesion for exploration.
