Frequencies of T cell subsets in peripheral blood of IBC patients compared to healthy controls. Absolute counts per μl of peripheral blood were determined for a CD4⁺ naive (CD62L⁺ CD45RA⁺) T cells, b CD4⁺ effector (CD62L⁻ CD45RA⁺) T cells, c CD4⁺ effector memory (CD62L⁻ CD45RA⁻) T cells, d CD4⁺ central memory (CD62L⁺ CD45RA^-) T cells, e CD8⁺ naive T cells, f CD8⁺ effector T cells, g CD8⁺ effector memory T cells, and h CD8⁺ central memory T cells. Healthy donors are shown as open circles, triple-negative IBC patients as shaded triangles, untreated IBC patients as filled squares, and chemotherapy-treated IBC patients as open squares. Horizontal lines indicate median values and statistical significance was determined by a Wilcoxon rank-sum test
