Independent Predictors of Overall Survival and Recurrence-Free Survival in Cox’s Analysis
| Category | Hazard rate | 95% CI | P* |
|---|---|---|---|
| Overall survival | |||
| Tumor thickness (>1.5 mm vs. ≤1.5 mm) | 3.41 | 1.67–7.01 | 0.0008 |
| Bleeding (yes vs. no) | 2.45 | 1.04–5.78 | 0.0411 |
| Recurrence-free survival | |||
| Tumor thickness (>1.5 mm vs. ≤1.5 mm) | 2.46 | 1.44–4.21 | 0.001 |
| CD44 expression (≤90 vs. >90%) | 1.74 | 1.05–2.87 | 0.0308 |
| Bleeding (yes vs. no) | 1.93 | 1.05–3.56 | 0.0346 |
Multivariate analysis included 251 patients with a complete set of data available. CI, confidence interval.
