a: Survival curves of the high-risk and low-risk groups in the age group <60 years, b: Survival curves of the high-risk and low-risk groups in the age group＞60 years, c: Survival curves of the high-risk and low-risk groups in the male group, d: Survival curves of the high-risk and low-risk groups in the female group, e: Survival curves of the high-risk and low-risk groups in the stage Ⅰ-Ⅱ group, f: Survival curves of the high-risk and low-risk groups in the stage Ⅲ-Ⅳ group. It can be seen from the above survival curve results of different groups that the risk score has a good predictive effect on the survival of HCC patients of different genders, ages, tumor stages, and grades.
