| Variable | Adjusted HR | 95% CI | P value |
|---|---|---|---|
| Age (years) | 0.081 | ||
| <60 | 1 | ||
| ≥60 | 0.497 | 0.228–1.085 | |
| Histology | 0.40 | ||
| Endometrioid | 1 | ||
| Non-endometrioid | 1.497 | 0.590–3.800 | |
| Initial stage | 0.30 | ||
| I/II | 1 | ||
| III/IV | 1.613 | 0.658–3.953 | |
| TFI | 0.042 | ||
