Table 3

5-year and 10-year survival rates for overall survival and recurrence-free survival.

	5-year survival rate (95% CI)	10-year survival rate (95% CI)
Overall survival
Low breast density (<25%)	0.97 (0.94–1.00)	0.95 (0.91–0.99)
Intermediate breast density (25–50%)	0.89 (0.80–0.99)	0.82 (0.71–0.96)
High breast density (>50%)	0.83 (0.72–0.96)	0.78 (0.65–0.93)
Recurrence-free survival
Low breast density (<25%)	0.97 (0.94–1.00)	0.92 (0.85–0.98)
Intermediate breast density (25–50%)	0.93 (0.86–1.00)	0.88 (0.79–0.99)
High breast density (>50%)	0.81 (0.69–0.95)	0.78 (0.65–0.93)
