Prognostic values of CD8 and CD103 expressions in tumor tissues for the patients with HCC or ICC. Kaplan–Meier survival analysis was performed to predict the prognostic values of tumor-infiltrating CD8⁺T cells and CD103⁺ immune cells in human HCC or ICC tissues. A, B, D, and E Patients were stratified according to the infiltration intensities of tumor-infiltrating CD8⁺T cells or CD103⁺ immune cells (high infiltration in red and low infiltration in blue). C and F Patients were categorized into four subpopulations as CD8^high CD103^high (green), CD8^high CD103^low (black), CD8^low CD103^high (red), and CD8^low CD103^low (blue). Cutoffs for low and high expressions were defined with the Cutoff Finder method. *P < 0.05, **P < 0.01
