Accordingly, the risk score of GBM patients could be calculated by the following formula: Risk score = AC012615.1 expression × (− 0.453878786202157) + LINC00957 expression × 0.0828358815945787 + LINC02532 expression × 0.355210689402953 + LINC00634 × (− 0.220300418653349) + POM121L9P expression × 0.376871997524452 + SNHG11 × 0.598418567613137 + USP32P3 expression ×  (− 0.284320135850659). Here, SMIM45 is linked to glioblastoma.
