Results Due to the fact that at the time of writing this article the project is still implemented, it is not possible to describe all its results. The preliminary results of the project achieved in 2017 are presented below.Validation of the research tool A total of 1,008 children and adolescents from the target group participated in the validation study. In outpatient examination AR was diagnosed in 46.4% and BA in 11.2%. The BA and AR risk assessment based on the original version of the algorithm is presented in Figure 2. On the basis of the data obtained during the validation study, the algorithm was calibrated to better match the specificity of the target group. The standard screening test division into two groups: probably healthy (negative result) and probably sick (positive result) was also adopted. Therefore, it was possible to determine the sensitivity and specificity of the new version of the algorithm. In the case of AR, the sensitivity of the diagnostic test was 0.852 and the specificity was 0.840. In the case of BA, it was 0.841 and 0.912, respectively. The detailed classification method is presented in Figure 3.
