Statistical tests, comparing characteristics of malignant lesions where diagnosis was provided by radial EBUS with non-diagnostic procedures

Variable	Radial EBUS (+)	Radial EBUS (−)	Statistics
Lesion size	40 (13–90)	31.5 (14–70)	p=0.075*
Distance PPL-pleura	15 (0–68)	12 (0–70)	p=0.415*
Distance PPL-carina	63.5 (10–127)	61 (8–135)	p=0.658*
Upper lobe	24	22	p=0.745**
Lower lobe	15	16

Non-parametric statistical tests used for lesion size, distance to pleura, and carina.
