Results of the interrupted time series regression on the association between independent variables calendar year and an interaction term for calendar year and the availability of MSP and breast cancer mortality. The analysis was performed based on combined data from all 14 western European countries considered in this study. Results are presented for the three defined age groups (50–59, 60–69, 70–79) separately.
