| Univariable Cox regression | ||
|---|---|---|
| Independent variables | HR (95% CI) | P value |
| Age | 1.02 (1.02-1.118) | .005 |
| Sex | 0.60 (0.23-1.604) | .310 |
| Gd+ volume | 1.09 (1.02-1.163) | .012 |
| 18F-FET-PET volume | 1.03 (1.01-1.059) | .006 |
| Residual fluorescence | 5.77 (1.59-20.96) | .008 |
| MGMT methylation | 0.47 (0.18-1.24) | .125 |
Results are reported as hazard ratios, 95% confidence intervals and P-values from Wald-tests. Gd+ gadolinium contrast enhancing tumor; MGMT O6-methylguanine-DNA methyltransferase.
