Kaplan–Meier survival curve shows that the ccRCC patient subgroup without AOX1 DNA deletion (CNA ≥ 0) has a survival advantage over that with AOX1 DNA deletion (CNA < 0) (CNA ≥ 0 vs. CNA < 0 HR: 0.25, 95% CI: 0.11–0.56) (Figure 6C). The gene discussed is AOX1; the disease is nonpapillary renal cell carcinoma.
