Prognostic significance of the levels of LAG-3⁺ cells, CD8⁺T cells, PD-L1 on TC, PD-L1 on IC,FGL1 on TC and FGL1 on IC in HCC patients. OS (a–f) and DFS (g–l) of HCC patients based on the levels of LAG-3⁺cells and CD8⁺T cells, PD-L1 and FGL1 status on TC and IC. Survival curves were assessed by the Kaplan–Meier method, and differences between groups were evaluated using log-rank test. The number of patients at risk was reported. TC tumor cells, IC immune cells
