Association between the expression of key lncRNAs and clinicopathological features in clear cell renal cell carcinoma (ccRCC). Statistically significant differences in the expression of these key lncRNAs were associated with various clinicopathological features: tumor stage (T1/T2 vs. T3/T4), distant metastasis (M0 vs. M1–X), cancer status (tumor free vs. with tumor), clinical stage (I/II vs. III/IV), and grade. The different lncRNAs are arrayed along the x-axis, while the y-axis indicates normalized expression (log2). *P < 0.05; **P < 0.01; ***P < 0.001
