Controlled Terminology

CDISC Controlled Terminology is the set of CDISC-developed or CDISC-adopted standard expressions (values) used with data items within CDISC-defined datasets. The CDISC Terminology Team, in collaboration with the National Cancer Institute's Enterprise Vocabulary Services (EVS), supports the controlled terminology needs of all CDISC foundational standards (SDTM (Drugs and Devices), CDASH, ADaM, SEND) and all CFAST disease/therapeutic area standards.
