Univariate Analyses of Early-Stage Breast Cancer Survival to Prognostic Factors in Breast Cancer
| Parameter | Range or category | Hazard ratio (95% confidence interval) |
|---|---|---|
| BRE | 1–3 | 0.876 (0.726–1.057) |
| TIMP-4 score | Positive vs. negative | 1.389 (1.012–1.907) |
| Tumor size | 5–20 mm | 0.984 (0.943–1.029) |
| ER | Positive vs. negative | 1.104 (0.690–1.687) |
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.
