confidence interval [CI] = 38.2% to 65.0%), 94.3% (95% CI = 94.1% to 94.5%), 5.7% (95% CI = 5.5% to 5.9%), and 1.0% (95% CI = 0.7% to 1.5%), respectively. The agestandardized incidence rates for early-stage (stage IIA or lower) breast cancer were 18.8 and 8.1 per 100 000 women and for advanced-stage (stage IIB or higher) breast cancer were 19.6 and 21.7 per 100 000 women, in the intervention and control groups, respectively.
