Moreover, we conducted DFS analysis in subgroups of ccRCC patients and low NBR1 expression could be a potential prognostic factor for ccRCC patients with non-metastasis (Figure 5B, p = 0.0017), T1 + T2 stage (Figure 5C, p = 0.01), N0 stage (Figure 5D, p = 0.0036), TNM (I+II) (Figure 5E, p = 0.0398), G3+G4 stage (Figure 5F, p = 0.0004), Male (Figure 5G, p = 0.0008), Age > 60 years (Figure 5H, p = 0.0076), Age ≤ 60 years (Figure 5I, p = 0.0066). Here, NBR1 is linked to nonpapillary renal cell carcinoma.
