Schematic diagram of the ECM-related prognostic signature construction and characterization. (A) The differentially expressed ECM genes were identified in CC through differential expression analysis. (B) ECM-related gene signature was constructed using training cohort. (C) ECM-related risk model was validated in various validation cohorts. (D) A new nomogram was constructed and validated. (E) Immune cell infiltration was analyzed. (F) Protein expression validation using Human Protein Atlas. TCGA, The Cancer Genome Atlas; COAD, colon adenocarcinoma; ECM, extracellular matrix; DEG, differentially expressed gene; KEGG, Kyoto Encyclopedia of Genes and Genomes; GO, gene ontology; Lasso, least absolute shrinkage and selection operator; KM, Kaplan-Meier survival analysis; ROC, receiver-operating characteristic.
