Association of CD8⁺CD28⁻ T cell proportion with systemic immune biomarkers in blood. a Correlation scatter plot between IL-1 and the CD8⁺CD28⁻ T cell proportion. b Correlation scatter plot between IL-5 and the CD8⁺CD28⁻ T cell proportion. c Correlation scatter plot between IL-10 and the CD8⁺CD28⁻ T cell proportion. d Correlation scatter plot between CD8⁺CD28⁻ T cell proportions. e In the group with a high level of pretreatment CD8⁺CD28⁻ T cells in peripheral blood, the increase in CD3⁺HLA-DR⁺ activated T cells after radiotherapy was significantly lower than that in the group with a low level of CD8⁺CD28⁻ T cells
