5 CDISC Standards

6 CDISC Standards Operational Data Model (ODM) Submission Data Standard (SDS) Study Data Tabulation Model (SDTM) Laboratory Data Model (Lab) Define.XML (Machine-readable Define.pdf content definition) Analysis Data Model (ADaM) Protocol Representation Group (PR) Standard Exchange of Non-clinical Data (SEND)

7 CDISC ODM Operational Data Model (Clinical Trials) Data recording / transfer Closely models current paper forms Driven by domain experts and technicians

8 CDISC ODM Contains both metadata and (clinical) data Metadata Study-related (protocol, forms, users, locations) Table and Column Data NOT confined solely to clinical data
