Race	No. of participants in the intervention group whose disease recurred	No. of participants in the comparison group whose disease recurred	Breast cancer events, HR (95% CI)	P value	No. of deaths in the intervention group	No. of deaths in the comparison group	Mortality, HR (95% CI)	P value
Asian*	6/46	3/50	2.09 (0.52 – 8.49)	0.300	4/46	4/50	0.85 (0.20 – 3.50)	0.819
African-American*	14/61	8/57	1.61 (0.67 – 3.87)	0.288	10/61	6/57	1.45 (0.52 – 4.03)	0.477
Hispanic†	13/87	16/78	0.67 (0.31 – 1.43)	0.362	8/87	10/78	0.70 (0.26 – 1.87)	0.479
white‡	216/1306	223/1328	0.98 (0.82 – 1.19)	0.864	127/1306	133/1328	0.98 (0.77 – 1.30)	0.868

Note: Adjustments were made based on baseline differences between intervention and comparison conditions.

HR = hazard ratio; CI = confidence interval.

Survivors were followed for a mean of 7.3 years

^*Models were adjusted for baseline body mass index.

^†Models were adjusted for age at study entry, age at diagnosis, radiation treatment and menopausal status.

^‡Models were adjusted for anti-estrogen use.
