Overall and disease-free survival rate among long-term breast cancer survivors in Shanghai Breast Cancer Survival Study by nut consumption

	Overall (N=3449)			Disease-freea (N=3274)
	N/total deaths	5-year survival rateb (%)	P-value	N/eventsc	5-year survival rateb (%)	P-value

^a175 subjects whose events occurred before the dietary assessment were excluded for disease-free analyses

^bThe entry time was age at the dietary survey; i.e., approximate 5-year post breast cancer diagnosis; the 5-year survival rate is approximate to the 10-year pot-diagnosis survival rate among long-term breast cancer survivors.

^cEvents include breast cancer recurrence, metastasis, and death.
