There was also no statistically significant difference (p=0.920, p>0.05) in the survival rate based on PD-L1 level where the PD-L1 expression in tumor cells was grouped according to a tumor proportion score of <1%, 1-9%, 10-49%, and ≥50%, when evaluated using the log-rank test (Figure 3). This evidence concerns the gene CD274 and neoplasm.
