PPI network and survival analysis. a Based on the STRING online database, 13 intestinal flora-related DEGs were filtered into PPI network. b The most significant module from the PPI network. c Kaplan–Meier curves of overall survival for patients grouped by expression level of CXCL8. PPI, protein–protein interaction; DEGs, differentially expressed genes; CXCL8, chemokine (C-X-C motif) ligand 8
