Figure 3. Screening, expression levels, and lncRNA-mRNA networks of eight TR-related lncRNAs in predicted signals. (A) Ten-fold cross-validation error rate plots. (B) LASSO coefficient profiles of TR-related lncRNAs. (C) Expression levels of eight TR-related lncRNAs in ccRCC and normal tissues. (D) Co-expression networks of prognostic TR-related lncRNAs. (E) Multinomial plots of prognostic TR-related lncRNAs. Abbreviations: lncRNAs: long-chain non-coding; ccRCC: renal clear cell carcinoma.
