SERPINH1 and nonpapillary renal cell carcinoma: The results revealed that the SERPINH1 expression level indeed predicted the OS and DFS time of ccRCC patients and could independently predict the prognosis of ccRCC patients (Low versus High; HR 0.696 and 0.433, 95% CI: 0.497–0.974 and 0.251–0.747, respectively, both P < 0.05, Fig. 4).
