The top three sIRlncRs (ATP1A1-AS1, IL10RB-DT and MELTF-AS1) among the 7 sIRlncRs were included to establish the IRRS model, by which the ccRCC samples were divided into the high-risk group and the low-risk group (Fig. 2a). This evidence concerns the gene MELTF and nonpapillary renal cell carcinoma.
