PD-L1-positive tumour cells detected by E1L3N correlated with positive tumour-infiltrating lymphocytes (R2 = 0.62 p = 0.001) (Fig. 1d; Supplementary Fig. 3 and Supplementary Tables 2, 3), and with larger tumour sizes (p = 0.014) (Fig. 1e and Supplementary Table 1), but not with overall survival or recurrence rate. This evidence concerns the gene CD274 and neoplasm.
