  • Other Information:
    • When different arms have different workflows, each of them will reference a different WorkflowDef element under MetaDataVersion. In the case where all arms have the same workflow (e.g., in a double-blind study), a single WorkflowDef element under MetaDataVersion can describe the common workflow. In such a case every arm will reference the same workflow.
    • A CDISC SDTM Trial Design element (the basic building block in the SDTM trial design) will be represented by a StudyEventGroup referenced from the arm workflow.
