CDISC-ADaM Models

CDISC ADaM team has defined four classes of ADaM datasets: ADSL (Subject-Level Analysis Dataset), BDS (Basic Data Structure), ADAE (Adverse Events Analysis Dataset), and OTHER. The ADAE class is soon to be generalized into the OCCDS (Occurrence Data Structure) class.

CDISC’s Analysis Data Model (ADaM) is a bit different than SDTM and SEND. It still has a core model and an implementation guide, but the model is not as proscriptive. Additional variables can be added within certain constraints defined by the model. This gives it the flexibility to be used for any type of analysis while providing a level of standardization that allows it to be easily understood by reviewers.
