This is an example of an ADLB dataset and is based on input from the SDTM LB dataset. This is just an example and does not mean to indicate that ADLB must be used as the dataset name nor are the parameters described necessarily the ones that would be used in a particular study.
This is an example SDTM datasets used to create the ADLB dataset. Only variables needed for illustration are shown in the examples.
