The validation for clinical application of the prognostic classifier associated with thrombus. (A) Differences in protein expressions of the six hub genes between normal and tumor tissues based on Wang’s external dataset. (B) Immunohistochemistry analysis of the six hub proteins in tumor tissue of ccRCC patients. (C) The Kaplan–Meier curve for disease-free survival of ccRCC patients with IHC-based high- or low-risk scores in a cohort of 40 cases. (D) The receiver operating characteristic curve for the IHC-based prognostic classifier predicting 3-year disease-free survival of ccRCC patients. *p < 0.05, **p < 0.01, ***p < 0.001.
