Table 3. Differences in each variable between successful and failed groups of cancer diagnosis.

Variables	Total (n=351)	Success (n=239)	Failed (n=112)	P value
Core tissue percentage (%)	100.00 (75.00–100.00)	100.00 (75.00–100.00)	100.00 (100.00–100.00)	0.273
Maximal diameter (cm)	1.50 (1.00–1.75)	1.50 (1.00–2.00)	1.00 (1.00–1.50)	0.016
Volume (cm3)	0.30 (0.12–0.68)	0.45 (0.20–0.68)	0.20 (0.10–0.45)	0.002

Core tissue percentage is defined as the percentage of core tissue adequately obtained from the total puncture attempts. Maximal diameter was the longest dimension of the obtained core tissue. Volume was estimated by multiplying the length, height, and width of the tissues. Data are presented as median (interquartile range).
