Development and evaluation of the vascular infiltration, pathological grade, and clinical stage-related lncRNA promoter methylation model. a Vascular infiltration-related lncRNA promoter methylation sites were screened by LASSO-COX method. b The coefficients of each methylation sites were determined by LASSO-COX method. c ROC curve analysis of vascular infiltration-related lncRNA promoter methylation model to evaluate vascular infiltration in HCC patients. d Pathological grade-related lncRNA promoter methylation sites were screened by LASSO-COX method. e The coefficients of each methylation sites were determined by LASSO-COX method. f ROC curve analysis of pathological grade-related lncRNA promoter methylation model to evaluate pathological grade in HCC patients. g Clinical stage-related lncRNA promoter methylation sites were screened by LASSO-COX method. h The coefficients of each methylation sites were determined by LASSO-COX method. i ROC curve analysis of clinical stage-related lncRNA promoter methylation model to evaluate clinical stage in HCC patients
