Figure 3. Association of T stage, N stage and tumor grade with overall survival in the low and high immune score groups. T stage was associated with overall survival in the low immune score group (A), but not the high immune score group (B). N stage was associated with overall survival in low immune score group (C), but not in high immune score group (D). Tumor grade was not associated with overall survival in low (E) or high (F) immune score group.
