Example of joining datasets based on built-in relationships. Results from related data sources can be joined into a common grid view using built-in relationships between study entities. Here, the grid view customization tool is used to pull in columns from data sources that include the same participant/visit pairs. The results of an assay ("Lab Results") are joined with the columns from another assay ("HIV Test Results") and the results of a physical exam ("Physical Exam"). The joined custom view can be saved privately, made visible to collaborators or exported in various formats, including Excel.
