PD-L1 expression patterns correlated with different TMEs. a Venn diagram analysis of differentially expressed genes between different PD-L1 expression patterns. b Top ten GO terms from the GO enrichment analysis using the common differentially expressed genes between Pattern 2 versus Pattern 1 and Pattern 4 versus Pattern 3. c Gene Set Enrichment Analysis using microarray data of one arbitrary PD-L1 expression pattern versus the other patterns. Selected gene sets are shown. NES normalised enrichment score, NOM p nominal p value, FDR q false discovery rate
