As shown in Figure 4, the high expression of TGFB1 (logrank p=0.0037), TIMP1 (logrank p=3.7e-05), and VIM (logrank p=0.048) indicated a poor prognosis for ccRCC patients, while the high expression of CCND1 (logrank p=6.7e-05) indicated a favorable prognosis for ccRCC patients. Here, TGFB1 is linked to nonpapillary renal cell carcinoma.
