A Guide to the ADaM Basic Data Structure for Dataset …
For the purposes of this paper, all data values in Study Data Tabulation Model (SDTM) datasets are considered to be observed. This is despite the fact that in actuality a data value may have been derived prior to or during the creation of the SDTM datasets. For example, an SDTM value of LDL cholesterol derived by the Friedewald calculation from
