Kaplan-Meier plot for CD28⁺CD28⁻ T-cell and clinical information relationship. a Kaplan-Meier plot for the proportion of CD8⁺CD28⁻ T cells for DMFS in the training cohort. b Kaplan-Meier plot for the proportion of CD8⁺CD28⁻ T cells for DMFS in the validation cohort. c Kaplan-Meier plot for CD8⁺CD28⁻ T cells combined with EBV DNA for DMFS. The purple line represents a low proportion of CD8⁺CD28⁻ T cells and EBV < 1500; the yellow line represents a high proportion of CD8⁺CD28⁻ T cells and EBC < 1500; the red line represents a low proportion of CD8⁺CD28⁻ T cells and EBC > 1500; and the blue line represents a high proportion of CD8⁺CD28⁻ T cells and EBC > 1500. d Kaplan-Meier plot for the proportions of CD8⁺CD28⁻ T cells in stage I/II patients. e Kaplan-Meier plot for the proportions of CD8⁺CD28⁻ T cells in stage III patients. f Kaplan-Meier plot for the proportions of CD8⁺CD28⁻ T cells in stage IV patients. The yellow line represents a low proportion of CD8⁺CD28⁻ T cells, and the blue line represents a high proportion of CD28⁺CD28⁻ T cells
