Positive framing. Out of 1,000 women aged 50 to 69 years invited every second year, 781 are alive with screening and the same number without screening over the course of 20 years. Correspondingly, 985 women and 982 to 983 women without screening will not die of breast cancer aged 55 to 74 years. Negative framing: out of 1,000 women aged 50 to 69 years invited every second year, 204 women will die with screening and the same number without screening. Correspondingly, 15 women with screening and 17 to 18 women without screening will die of breast cancer between 55 and 74 years old. Number of women dying among women aged 55 to 74 years is based on the observed mortality rates in England and Wales in 2007 [68]. The number of women dying over a 20-year period is estimated by summing the mortality rates for the ages 55 to 74 [68].
