Regarding ICs markers, in the W‐L group, we observed a nonstatistically significant slight inverse correlation between the frequency of CD4+PD‐1+ T cells in GBM and the patient's OS (Figure S4A), that was more evident and near to statistical significance (p = 0.06) considering only PD‐1 single positive cells (PD‐1+TIGIT–) (Figure S4B). The gene discussed is CD4; the disease is glioblastoma.
