mVisualizer – for visualisation of the database

The application is used for visualization and statistical analysis of the database. The entire database or a selection according to predefined criteria is opened. The group selected can then be subjected to various forms of statistical analysis, which generates numerical values but also a visualized result of the analysis. New selections can also be performed within the diagram and subjected to further analysis by a “click-and-drag” procedure. The characteristics of the second selection are then visualized in a new diagram, and the application also enables the possibility to see clinical images and text information of the individual patients. mVisualizer enables statistical analysis, but the programme does not in itself contain statistical programmes. The data or numerical values obtained from the chosen analysis are transferred to a spreadsheet, which can be saved in the form of an Excel-file. This file can then be imported into a statistical programme for subsequent statistical analysis.

Some topics generate hundreds of possible values. From the aspect of analysis, it would be extremely difficult to analyze the database if individual values could not be assembled into larger groups. The Aggregator was designed for this purpose and permits clustering of input data into a separate category. In this example the yellow bar contains an aggregate of the VAS-values 5 to 10. The structure of the clustering is saved and stored in a separate file and can be used by other members of the network. This application is also well suited for the situation where international differences in nomenclature exist in multicenter trials. Differences in nomenclature can be overcome by aggregating the chosen values into suitable categories.
