Figure 1. Distribution of Race for Members in the CVRN VTE Dataset
All member data was extracted using the Virtual Data Warehouse (VDW). The VDW is a standardized resource comprised of: (1) computerized datasets stored behind separate security firewalls, including variables with identical names, formats, and specifications; (2) informatics tools that facilitate storage, retrieval, processing, and managing the datasets; and (3) detailed data documentation. All data are linked by a unique identifier so that data elements can be rolled up to the individual person-level.
