High-risk group associated with tumor immune-infiltration phenotype and a low level of oxidative phosphorylation. A The study of single-sample gene set enrichment (ssGSEA) assesses the activity of oxidative phosphorylation, TCA cycle and alanine_aspartate_glutamate metabolic pathway in each PC sample and analyses the differences in the levels of this pathway between high- and low-risk groups, (⁻P > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001). B The differences in the level of infiltration of 29 immune cell species between different risk groups were examined using ssGSEA in the TCGA-PAAD cohort. C The differences in the level of infiltration of 29 immune cell species between different risk groups were examined using ssGSEA in the ICGC-PAAD cohort
