Multivariable logistic regression analysis of risk factors for ALN metastasis
| Intercept and variable | Combined model in the training cohort | ||
|---|---|---|---|
| Coefficient | Odds ratio (95% CI) | P value | |
| Intercept | −2.586 | 0.073 (0.003–0.100) | 3.23 × 10−5 |
| Histological grade | 1.012 | 2.751 (1.614–4.877) | 3.11 × 10−4 |
| Multifocality | 1.331 | 3.783 (1.941–7.601) | 1.26 × 10−4 |
| MRI report LN status | 1.083 | 2.954 (1.537–5.821) | 1.37 × 10−3 |
| Radiomics signature | 1.927 | 6.871 (4.121–12.617) | 1.25 × 10−11 |
Note: Data in parentheses are 95% confidence intervals. P value are displayed as scientific notation. The combined model was established based on these risk factors related to the axillary lymph node metastasis, while the clinical model without radiomics signature
