Multivariate logistic analysis of factors influencing pCR in TNBC patients underwent neoadjuvant chemotherapy

Variables	OR	95% CI	P-value
Tumor size before NAC (cT1-cT2 vs cT3-cT4)	4.375	1.353-14.151	0.014
LNS before NAC (N0-N1 vs N2-N3)	0.636	0.248-1.631	0.347
LVI status (Negative vs Positive)	2.545	0.949-6.830	0.064
TAM infiltration (Low vs High)	3.333	1.117-9.946	0.031

TAM: tumor-associated macrophages; LNS: lymph node status; LVI: lymphovascular invasion; OR:Odds ratio; CI: confidence interval.
