Survival analyses by the Kaplan–Meiermethod. (a) The OS of CD47+ cases (± and +cases) was significantly shorter (P=0.015). (b) Increases in the infiltration of CD68+ macrophages in SCCHN tissue were associated with shorter OS (P=0.035). (c, d) Overall (c, P=0.025) and progression-free (d, P=0.011) survivals correlated with the infiltration of CD163+ M2.
