YAP1 and non-small cell lung carcinoma: The PD-L1 mRNA expression level was not associated with any clinical parameters in these 46 NSCLC patients (Supplementary Table 1); however, a positive correlation was observed between PD-L1 and YAP1 mRNA expression in this study population, as high-PD-L1 mRNA tumors were frequently also high-YAP1 mRNA tumors (69.6% vs. 30.4%, P = 0.008; Table 1).
