Analyze distribution chart data

The distribution chart visualizes the frequency of coded values across different categories or variables. It provides a clear representation of coding practices and helps identify trends, potential issues, and the overall performance of coding efforts.

In EDC, the Distribution chart is represented with a bar chart. The bar chart is a graphical representation of data using rectangular bars to show the magnitude of different categories or groups. In the Distribution chart, the x-axis of the bar chart typically represents specific codes, terms, or categories that are being analyzed. This might include MedDRA terms, WHODrug terms, or other predefined coding categories, whereas y-axis represents the frequency count or the number of instances for each term or category.

    Tip

    To enlarge the table view, from the chart, switch to the Full Screen Full_screen_icon.png mode.

Once you have analyzed the details of the Distribution chart, select Detail_icon_enabled.png to close the table and return to the chart view.

An internationally used set of terms relating to medical conditions, medicines, and medical devices created to assist regulators with sharing information.

A coding service that is used for the unified coding of drugs throughout the pharmaceutical industry. In order to achieve this, the service provides the WHODrug dictionary which is an international classification of medicines created by the WHO Program for International Drug Monitoring. The dictionary is managed by the Uppsala Monitoring Centre and contains drug code numbers, along with related information such as trade names, active ingredients, and additional information, such as marketing authorization, pharmaceutical forms, and strengths of the drugs.

For example, the WHODrug drug code for the substance Ibuprofen is 001092 01 001.
