Table 3.

Scoring criteria used by radiologists to evaluate the contours for qualitative analysis.

	Likert scale	Criteria
5	Strongly agree	Minor edits which are not clinically important, or no edits are required. Can use the contours in the clinic without any edits
4	Agree	Minor edits (peripheral portal veinous branches) are required, and the time required to recontour is minimal
3	Neither agree nor disagree	Major edits (Major vessels (hepatic veins, right/left/main portal, and segmental portal vein branches) boundaries and anatomical boundaries (intersegmental fissure and gall bladder fossa) need to be corrected) but time required to recontour is minimal
2	Disagree	Major edits are required, and the time required to edit the contour is extraordinarily long
1	Strongly disagree	Segmentations are unusable
