Subgroup analysis showed that OS was significantly shorter in ccRCC patients with low DAPK1 expression compared to those with higher DAPK1 expression belonging to G3 + G4 (Figure 2B, N=285, P=0.0214) and M0 stages (Figure 2C, N=425, P=0.0361). Here, DAPK1 is linked to nonpapillary renal cell carcinoma.
