Identification and validation of extracellular matrix-related genes in the progression of gastric cancer with intestinal metaplasia

Figure 4 The establishment and validation of prognostic models. A: Nomogram and prognostic calibration curve constructed based on clinical tumor node metastasis stage, age, and hub genes; B: Risk factor plot based on secreted protein acidic and rich in cysteine/SERPINE1 expression and risk score in the Cancer Genome Atlas-stomach adenocarcinoma dataset; C: Prognostic analysis and Kaplan-Meier curve for the two risk groups; D: Prognostic receiver operating characteristic curves at 1-year/2-year/3-year based on secreted protein acidic and rich in cysteine/SERPINE1 risk scores in the The Cancer Genome Atlas-stomach adenocarcinoma dataset; E: The decision curve analysis curve; F: The clinical impact curve. HR: Hazard ratio; TPR: True positive rate; FPR: False positive rate; AUC: Area under the curve; SPARC: Secreted protein acidic and rich in cysteine.
