CDKN2B and hepatocellular carcinoma: With P < .05, four lncRNAs (RP11‐284F21.10, RP11‐284F21.7, MAFG‐AS1, and CTC‐297N7.9) were revealed to have significant association with OS, and three lncRNAs (RP11‐284F21.9, CDKN2B‐AS1, and CTC‐297N7.9) were shown obvious relevance to DFS of patients with HCC (Table S3).
