Nomogram depicting 1-, 2- and 3-year recurrence-free survival probability. By drawing a line between each variable and the uppermost component points, the appropriate points can be assigned to five variables. The sum of these five points can be expressed on the total point line. The 1-, 2-, and 3-year recurrence-free survival probability can be calculated by connecting each point to the survival line. The exact values of individual factors are tumor thrombus (100, 0 points), cancer cell differentiation (92, 63, 0 points), HBsAg (68, 0 points), MVI (65, 0 points), and tumor number (63, 0 points). HBsAg hepatitis B surface antigen, MVI microvascular tumor invasion, RFS recurrence-free survival
