Multivariable logistic regression model for pCR

	Odds Ratio	95% CI	P
Bisphosphonates use: yes v. no	2.18	0.90 to 5.24	0.08
Age: ≥ 50 versus < 50	0.66	0.48 to 0.92	0.015
Stage: III vs I/II	0.69	0.5 to 0.96	0.026
Grade: III vs I/II	3.80	2.37 to 6.07	<.001
Subtype: HER2 positive vs Hormone positive	3.02	1.97 to 4.64	<.001
Subtype: Triple negative vs Hormone positive	2.66	1.8 to 3.93	0.011
LVI: positive vs negative	0.38	0.26 to 0.57	<.001
BMI: overweight vs normal	0.69	0.46 to 1.04	0.022
BMI: obese vs normal	1.09	0.75 to 1.59	0.10

pCR = pathologic complete response; HER2 = human epidermal growth factor receptor 2; LVI = lymphovascular invasion; BMI = body mass index; CI = confidence interval.
