To assess the ability of the IRlncRNA signature to predict the survival of BLCA, we calculated the risk score for each case according to the expression of eight IRlncRNAs: Risk score = (-0.27 * expression value of MIR181A2HG) + (-0.20 * expression value of AC114730.3) + (-0.27 * expression value of LINC00892) + (0.12 * expression value of PTPRD-AS1) + (0.16 * expression value of LINC01013) + (0.12 * expression value of MRPL23-AS1) + (0.18 * expression value of LINC01395) + (0.13 * expression value of AC002454.1). The gene discussed is LINC00892; the disease is bladder transitional cell carcinoma.
