FIGURE 4. Subgroup survival analysis. (A, B) First, the high-risk group continued to have a worse prognosis in different age groups. (C, D) The high-risk score was also a risk factor for poor prognosis in ccRCC patients in different gender groups. (E–L) Among patients with different grades, M stage, total stage, and T stage, the high-risk group of ccRCC patients continued to have a worse prognosis (**p < 0.01, ***p < 0.001).
