| TDT-line risk group (favorable vs intermediate vs unfavorable) | 2.41 (1.26-4.59) | .008 |
| DSPFSc | ||
| TDT-line risk group (favorable vs intermediate vs unfavorable) | 18.49 (3.96-86.24) | .0002 |
| Tumor location (lobes vs other) | 0.07 (0.01-0.33) | .0009 |
| OSb | ||
| Age (<70 vs ≥70) | 4.89 (1.27-18.80) | .02 |
| Tumor volume (<11 vs ≥11 cm3) | 4.32 (1.16-16.02) | .03 |
| DSOSc | ||
| TDT-line risk group (favorable vs intermediate vs unfavorable) | 6.30 (2.45-16.23) | .0001 |
| Age (<70 vs ≥70) | 10.99 (1.32-91.24) | .03 |
| Gender (Female vs Male) | 9.45 (1.10-80.89) | .04 |
PFS: progression-free survival, DSPFS: disease specific progression-free survival, OS: overall survival, DSOS: disease specific overall survival, C.I: confidence interval, TDT-line: thermal damage threshold line
aThe first group listed is the reference; ratios > 1 indicate the risk of death is greater in the second group; ratios < 1 that it is less. For NeuroBlate risk group the (sub) hazard ratio represents the increase in risk for a one category increment
