In this Section, "Statistics for screening", we want to emphasize that it is more and more important to use statistics to understand, to analyze and to evaluate the data of a screening, in order to describe the population and to take decisions and, even before, to learn to draw and design a screening itself.As highlighted by the title, using results from the project of mammography screening in the Province of Trieste, we want to focus in particular the importance of
- the quality of the data; without which it is no possible to make a correct statistics, and in this talk we show an example of the correction of the data concerning the blood group;
- the evaluation of the indicators, and here it is important to decide which are ‘informative indicators’, and how it is possible to read the output in a critical way;
- the impact of a screening on a population.
In this context it is evident the importance of a multidisciplinary work, and this is the experience started some years ago in our local reality, with the involvement of pathologists, surgeons, radiologists, radiotherapists, oncologists, physicists , mathematicians, statisticians, ... the different care and research contributions for breast disease in the province of Trieste.
