CD8A and neoplasm: Examples of CD8 staining and scores are shown in Fig. 2E. Patients were initially separated into 4 cohorts according to CD8 staining intensity (0,1,2 and 3, Fig. 2E), however there was only 1 tumor out of the 145 tumors that was assigned a CD8 score of 3 (Fig. 2E bottom right) and was thus included in the cohort assigned a CD8 score of 2.
