Spatiotemporal model estimates of age-specific breast cancer mortality in Switzerland from the 1969–1972 period to the 2009–2012 period. Bold values denote age-standardised mortality ratio significantly different from 1. Spatial variation (SD of spatial random effects): a value of 0 means that there is no spatial correlation
