Additional file 2 of Integrating heterogeneous data to address endemic diseases in broiler production: insights from a Polish case study

Additional file 2: Description of the grouping or data integration rule used to define the variable used in the analysis. The file is organised in a workbook containing four worksheets. The first worksheet describes the workbook. The second worksheet contains the logic tree used for data integration to define the evidence of virus circulation in the ‘screened flocks’ using available information from the results of the ELISA tests, RT-PCR and provided vaccines. The third worksheet presents the grouping logic used to define the forty variables under the 'necropsy lesion' theme used in the analysis. The last worksheet presents the grouping logic used to define the 19 variables in the theme 'bacteria status' used in the study.
