Establishment and validation of LMRGs prognostic signature for patients with EC. a Multivariate Cox regression analysis of LMRGs. b, c Risk score distribution and survival status of EC samples based on the risk score. d The PCA, based on all genes, lactate-related genes, and riskgenes, indicate that tumor samples and adjacent tissues are wellseparated by first principal component (PC1) and second principal component (PC2). e, f The Kaplan?Meier survival curves of OS and PFS according to high-and low-risk groups in patients with EC. g, h The univariate Cox regression and multivariate analysis of age, grade, stage, and risk score for OS. i ROC indicated the predictive accuracy of Riskscore was superior to other clinical parameters
