Development of a lipid metabolism-related gene model to predict prognosis in patients with pancreatic cancer

Figure 4 Prognostic analysis of 4-gene signature models in The Cancer Genome Atlas. A: Distribution of risk score values in The Cancer Genome Atlas (TCGA); B: Principal component analysis plot of the pancreatic adenocarcinoma (PAAD) cohort from TCGA; C: t-distributed stochastic neighbor embedding analysis of the PAAD cohort from TCGA; D: Distribution of overall survival status, survival time, and risk scores in the cohort from TCGA; E: The Kaplan-Meier curve presents the overall survival of patients in the high-risk and low-risk groups in the PAAD cohort from TCGA; F: The prognostic performance of the risk score in the PAAD cohort from TCGA was verified by the area under the curve of the time-dependent receiver operating characteristic curve. PC: Principal component; tSNE: t-distributed stochastic neighbor embedding.
