Various quantifications of VETC in patients with and without recurrent HCC.

VETC measure	Alln=158	Recurrent HCCn=13	No recurrencen=145	P
Patients with VETC-positive HCC	121 (76.6)	11 (84.6)	110 (90.9)	0.475
Number of viable HCCs on explant per patient  Number of VETC-positive HCCs per patient  Proportion of VETC-positive HCCs per patient	2.0 (1.0-2.0) 1.0 (0-1.0) 100% (50-100)	3.0 (2.0-3.5) 2.0 (1.0-2.5) 100% (45-100)	1.0 (1.0-3.0) 1.0 (1.0-1.0) 100% (50-100)	0.007 0.016 0.872
Highest (worst) VETC index found per patient	1.6 (0.1-9.1)	2.6 (0.4-34.4)	1.4 (0.1-8.0)	0.279
Sum of VETC indices across all HCCs per patient	1.7 (0.1-9.4)	4.2 (0.6-43.0)	1.7 (0.1-8.9)	0.193
Average VETC index per HCC per patient	1.1 (0.1-6.4)	1.5 (0.3-10.7)	1.1 (0.1-6.3)	0.397

The data are shown in number (percentage) and median (interquartile range).

HCC, hepatocellular carcinoma; VETC, vessels that encapsulate tumor clusters.

The bold values are the significant values (where P<0.05).
