| Characteristic | TSS | DFS | ||
|---|---|---|---|---|
| Adjusted HR (95% CI) | p value | Adjusted HR (95% CI) | p value | |
| Advanced age (≥65) | 4.492 (1.320–15.294) | 0.016 | 3.267 (1.252–8.528) | 0.016 |
| High grade (grade 3) | 4.547 (1.453–14.225) | 0.009 | 5.178 (2.131–12.581) | <0.001 |
| Positive peritoneal cytology | 10.982 (2.948–40.907) | <0.001 | 7.570 (2.607–21.979) | <0.001 |
| Advanced stage (stage III–IV) | 4.446 (1.456–13.576) | 0.009 | 4.110 (1.739–9.713) | 0.001 |
Bold-font values indicate p values less than 0.05, which is considered statistically significant.
DFS, disease-free survival; CI, confidence interval; HR, hazard ratio; TSS, tumor-specific survival.
