Three Kaplan-Meier plots were generated to compare treatment-associated survival rates between the antigen-positive (MDA-MB-231 PD-L1 OE) and the antigen-deficient (MDA-MB-231 PD-L1 KO) tumor challenge groups (treatment groups: MC9999 CAR T cells [Figure 2B], non-CAR T cells [Figure 2C], and PBS [Figure 2D]). This evidence concerns the gene CD274 and neoplasm.
