| Parameter | Range or category | Estimate | SE | χ2 statistic | P | Hazard ratio (95% confidence interval) |
|---|---|---|---|---|---|---|
| BRE grade | 1–3 | −0.13086 | 0.09909 | 1.7442 | 0.1866 | 0.877 (0.723–1.066) |
| TIMP-4 score | Positive vs. negative | 0.35253 | 0.16323 | 4.6643 | 0.0308 | 1.423 (1.032–1.959) |
| Tumor size | 5–20 mm | −0.01434 | 0.02324 | 0.3809 | 0.5286 | 0.985 (0.942–1.032) |
Statistical analyses were performed by the χ2 test (Wald method) in Cox proportional hazards regression analysis to evaluate the prognostic power of factors in a multivariate manner.
