Hi,
Based on Define V2.1 origin for SDTM dataset, please help to discuss the type of --STRESU for VS, LB，EG domain and so on, if the standard unit was not collected in the CRF. Here are 2 options, “Derived” or “Assigned”? Moreover, how about other ambiguous variables, such as AVISITN/PARAMCD/PARAMN?How to distinct the type of “Derived” or “Assigned”? Thanks!
Option 1: TYPE as “Derived”. Follow the Define-XML-2-0-Specification.pdf as below, the type of VSSTRESU is “Derived”.
Option 2: TYPE as “Assigned”. Follow the example from Define V2.1 as below.
