Table 1 Multivariate analysis of PD-1+ immune infiltrates and PD-L1 tumor cells with survival outcomes in patients with TNBC. Analysis was adjusted for tumor size, grade, age and lymph node status

From: Prognostic value of CD8 + PD-1+ immune infiltrates and PDCD1 gene expression in triple negative breast cancer
