Figure 4 shows the univariate overall survival analysis of A-DLBCL patients according to the expression of different markers, showing that patients with PD-L1+/mPD-L1+ or mPD-L1+ had significantly poorer overall survival(OS) than those with PD-L1- status(P=0.034 and P=0.046, respectively). Here, CD274 is linked to diffuse large B-cell lymphoma.
