Exposure (ADEX)

This is an example of an ADEX dataset and is based primarily on input from the SDTM EX dataset. Other administrative data about the subjects are based on the ADSL dataset provided in Section 3.3.6.1, Subject-level Analysis Dataset (ADSL).

Example

This is an example of the input SDTM EX dataset used to create the ADEX. Only variables needed for illustration are shown in the example.
