Results from Cox proportional hazards regression estimation (backward).
| Covariate | OR | 95% CI of OR | p |
|---|---|---|---|
| INI1 negativity | 4.11 | 1.39–12.15 | 0.0105 |
| IDH2 p.Arg172x | 5.99 | 1.74–20.69 | 0.0046 |
| Smoking habits | 3.50 | 1.35–9.07 | 0.0102 |
| LINE-1 hypermethylation | - | - | n.s. |
LINE-1 hypermethylation is excluded by the regression model, as it is not an independent variable (p > 0.1); indeed, it is associated with INI1 negativity and IDH2 p.Arg172x. OR: odd’s ratio; CI: confidence interval; n.s.: not significant.
