Findings Axillary radiological complete response predicted axillary pCR in univariate (p = 0.021) and multivariate analyses (p = 0.025), while Ki-67 was marginally significant in the multivariate model (p = 0.045) .

Although the Ki-67 index also showed a trend toward association with axillary pCR (OR = 0.96; 95% CI: 0.90–1.01, p = 0.117), it did not reach statistical significance on the univariate analysis.

On the univariate analysis, axillary rCR showed a strong association with axillary pCR (OR = 5.83; 95% CI: 1.30–26.12, p = 0.021) while the Ki-67 index demonstrated a trend toward significance (OR = 0.96; 95% CI: 0.90–1.01, p = 0.117).
