Subgroup analysis between the isolation and no-isolation groups

	All (n=76)	Isolation group (n=38)	No-isolation group (n=38)	P
Length of SVWC median, mm (range)	9 (0-99)	9 (1-99)	9 (0-59)	0.42
Median area of whitish core measured by AMUS, mm2, (range)	10 (0-75)	12 (1-75)	10 (0-70)	0.09
Median histological adequacy score, (range)	4 (0-5)	4 (2-5)	4 (0-5)	0.37
Median score of the degree of blood contamination, (range)	3 (1-3)	3 (2-3)	2 (1-3)	<0.01

The P values (isolation group vs. no-isolation group) were determined using the Mann-Whitney U test. SVWC: Stereomicroscopically visible white core; AMUS: Automated multiband imaging system
