Statistical results of the three procedures in secondary outcomes

Secondary outcome	Group Ab	Group Bc	Group Cd	P valuea
				A vs. B	A vs. C
Procedural time (second)	101.1 ± 31.3	87.1 ± 34.7	89.3 ± 33.6	<  0.001	<  0.001
Tissue-core acquisition (%)	47.1	49.4	32.5	0.576	< 0.001
The amount of bleeding (score)	1.97 ± 0.17	1.96 ± 0.20	1.97 ± 0.17	0.366	>  0.999

^aProcedural time, tissue-core acquisition rate, and the amount of bleeding were analyzed by the paired t-test, McNemar test, and the Wilcoxon’s test, respectively

^bA, suction–stylet procedure

^cB, suction–no stylet procedure

^dC, stylet–no suction procedure
