Figure 7. Independent prognosis analyses of TRPGs risk model in TCGA and GES14520 HCC cohorts. (A, B) Univariate and Multivariate Cox regression of risk score based on OS in TCGA HCC cohort. (C, D) Univariate and Multivariate Cox regression of risk score based on RFS in TCGA HCC cohort. (E, F) Univariate and Multivariate Cox regression of risk score based on OS in GSE14520 HCC cohort. (G, H) Univariate and Multivariate Cox regression of risk score based on RFS in GSE14520 HCC cohort. TRPGs, tryptophan metabolism-related genes; HCC, hepatocellular carcinoma; TCGA, The Cancer Genome Atlas; OS, overall survival; DSS, disease-specific survival; RFS, relapse-free survival.
