The results showed that the patients with ccRCC and high CTD-2396E7.11, RP11-298J20.4, RP5-994D16.9, and CTB-41I6.2 expression had better prognoses, while those with high AC006129.2, CTD-2510F5.4, and TUG1 expression had worse prognoses (Additional file 4: Figure S1; Additional file 5: Figure S2). Here, TUG1 is linked to nonpapillary renal cell carcinoma.
