PIWI-Interacting RNA Pathway Genes: Potential Biomarkers for Clear Cell Renal Cell Carcinoma

Figure 4

Risk score analysis of the 5 piRNA pathway genes prognostic risk model in the testing group ccRCC patients. (a) Kaplan-Meier survival curve analysis shows the overall survival of high- () and low-risk () testing group ccRCC patients based on the median risk score calculated using the 5 piRNA pathway genes prognostic risk model. (b) Time-dependent ROC curve analysis shows the prognostic performance of the 5 piRNA pathway genes prognostic risk model in predicting 1-year, 3-year, and 5-year survival times of the high- and low-risk testing group ccRCC patients. (c) Risk curve analysis of the 5 piRNA pathway genes prognostic risk model in high- and low-risk testing group ccRCC patients. (d) Scatter plots show the survival status of the 5 piRNA pathway gene prognostic risk model in the testing group ccRCC patients. (e) The heat map shows the expression of the 5 piRNA pathway gene prognostic risk model in high- and low-risk testing group ccRCC patients.
