In TCGA-PAAD and E-MTAB-6134 datasets, PD1 and CTLA4 expressions were significantly higher in low risk-score, than in high risk-score subgroups (Figure S13A, B), while differences in the ICGC-PACA-AU datasets were not statistically significant. The gene discussed is PDCD1; the disease is pancreatic adenocarcinoma.
