Blind validation Set
Peri-tumor	25	76.0% / 90.4%	1	19	5
Tumor	25	88.0% / 81.5%	0	3	22
Overall
Normal	10	100% / 90.9%	10	0	0
Peri-tumor	80	90.0% / 83%	2	72	6
Tumor	80	92.5% / 92.5%	0	6	74

Note: “Peri-tumor” is non-malignant liver tissue adjacent to the tumor; “Normal” is residual liver graft tissue.
