Construction of a PDK4-based prognostic model. A Univariate and multivariate Cox regression analyses of TOP1MT, PDK4, PGM5, and CYC1 levels with age, gender, race, pTNM stage, and grade in TCGA-STAD cohorts. HR and p values were displayed. B Nomogram by multivariate Cox regression analysis for predicting the proportion of patients with OS. C Plots depict the calibration of the model in terms of agreement between predicted and observed OS. D DCA of candidate mRNAs (PDK4, PGM5, and CYC1) for predicting survival status
