Correlations between different plasma biomarkers and the proliferation of CD8⁺ T cells. a peripheral Tregs subsets negatively correlated with the %divided of CD8⁺ T cells, p = 0.0225, r = − 0.379; g the degree of chemotherapy or radiotherapy induced lymphopenia were negatively correlated with the proliferation of CD8⁺ T cells, p = 0.0003, r = − 0.464; b–f no significant correlations were observed between other circulation T cells subsets or NLR and the proliferation of CD8⁺ T cells
