TMEM220 and glioma: The eight lncRNAs were combined to establish a risk score model for glioma patients, as follows: riskscore = (0.1434) ∗ AGAP2-AS1 + (0.1612) ∗ CYTOR + (4e − 04) ∗ MIR155HG + (−0.1641) ∗ LINC00634 + (0.0385) ∗ HOTAIRM1 + (0.0816) ∗ SNHG18 + (0.0141) ∗ LINC01841 + (0.0819) ∗ LINC01842 + (0.0016) ∗ LINC01426 + (−0.0282) ∗ MIR9-3HG + (0.0925) ∗ TMEM220-AS1 + (−0.1016) ∗ LINC00641 + (0.0768) ∗ LINC01270 + (0.0016) ∗ LINC01503 (Figure 3(a)).
