This directory contains data files and documentation for controlled terminology
used by the Clinical Data Interchange Standards Consortium (CDISC) to support
the Digital Data Flow (DDF) project.  It represents all DDF controlled 
terminology developed and in production to date. Additional terminology will be 
developed on an ongoing basis. Other future additions to the terminology set will 
also be handled via the terminology change request and maintenance process.

Background:

SDTM is an international standard for clinical research data, and is approved
by the U.S. Food and Drug Administration as a standard electronic submission
format.  CDISC and NCI work together to develop and maintain SDTM controlled
terminology, which is also integrated and distributed as part of NCI
Thesaurus (NCIt).
