Dot plots for proportions of pSTAT3-positive tumor cells according to PD-L1 protein expression in tumor cells and gene alteration status in diffuse large B cell lymphoma. PD-L1t+ PD-L1 GA− cases have higher proportions (%) of pSTAT3-positive tumor cells than the rest cases (PD-L1t− or PD-L1t+ PD-L1 GA+) (a), and this tendency was preserved in comparison of each subset (PD-L1t+ PD-L1 GA− vs. PD-L1t−; PD-L1t+ PD-L1 GA− vs. PD-L1t+ PD-L1 GA+) (b)
