How does CISNET modeling work?
In order to quantify the individual contributions mammography and adjuvant therapy have made to the decline in breast cancer mortality rates, seven different CISNET modeling groups used common data inputs and asked common questions about expected outcomes. For consistency in modeling, inputs included the patterns and extent of mammography and adjuvant therapy use, and questions sought information about outcomes such as improvement or decline in health with or without these two factors. This approach used population data to describe the extent and patterns of mammography and adjuvant therapy usage in the U.S. over time. The seven groups worked independently to develop their models but worked together to consider shared problems and to enable comparisons by developing uniform reporting methods. The usage patterns were then combined with all of the available information on the benefits of these advances that had been compiled by the seven independent modeling groups. The seven models diff
