The differentially expressed genes (DEGs) between the high- and low-risk groups were identified using the limma package (31). To better understand the functions of the DEGs in AML, we used the clusterProfiler package (22) for enrichment analysis, including the GO terms, including biological process (BP), molecular function (MF) and cellular component (CC), and KEGG pathways. The DEGs were clustered and a heatmap for them was generated via ClustVis (32).
