Construction and evaluation of a prognostic 19-ARG signature. A Hazard ratio in high and low expressions of ARGs in PRAD cohort, and corresponding 95% confidence intervals were calculated by the univariate regression analysis. B A 19-ARG signature was confirmed by the LASSO regression analysis with tenfold cross-validation. C Kaplan–Meier DFS curves for patients from the TCGA cohort in the high- or low-ARGs signature score group. D The ROC curves for DFS at 1, 3, and 5 years were analyzed in the TCGA cohort. E Kaplan–Meier DFS curves for patient samples assigned to high- and low-ARGs signature score in the validation group, GSE40272 from the GEO database. F The ROC curves for DFS at 1, 2, and 3 years were analyzed in GSE40272. G Kaplan–Meier DFS curves for patient samples assigned to high- and low-ARGs signature score in another validation group of the PRAD_MSKCC cohort. H The ROC curves for DFS at 1, 3, and 5 years were analyzed in the PRAD_MSKCC cohort
