The risk score for each HCC patient was calculated using the following formula: Risk Score = (0.6582 × LINC01134 expression) + (−0.5398 × HPN-AS1 expression) + (1.8022 × DDX11-AS1 expression) + (−0.8078 × AC009283.1 expression) + (0.368 × AC009005.1 expression). The gene discussed is LINC01134; the disease is hepatocellular carcinoma.
