Figure 3c and d shows that the overall survival and disease-free survival analysis (DFS) of ACOX1 expression were performed using the GEPIA database. The plots indicated that ccRCC patients with a decreased ACOX1 expression had poor OS (log-ranch test, P = 3.4 × 10−7; Figure 3c). The OS rate (log-ranch test, P = 0.0007) and disease-free survival (DFS: HR = 9.5 × 10−7) are shown in Figure 3d. This evidence concerns the gene ACOX1 and nonpapillary renal cell carcinoma.
