Table 3. Influence of time to adjuvant chemotherapy on disease-free survival in different subtypes.

Subtype	Hazard for time to adjuvant chemotherapy (≤8 vs. >8 weeks)
	Univariate P (log rank)	Multivariate HR (95% CI)#	Multivariate P
Luminal-A (n=667)	0.47	1.15 (0.54-2.43)	0.72
Luminal-B (n=328)	0.016	1.93 (1.10-3.34)	0.020
TNBC (n=270)	0.007	2.55 (1.25-5.18)	0.010
HER2+ (n=143)	<0.001	2.41 (1.36-4.26)	0.009
