Controlled Terminology

CDISC Controlled Terminology is a set of standard value lists that are used throughout the clinical research process, from data collection through analysis and submission. Controlled terminology is updated quarterly by the CDISC Terminology Team and published by the National Cancer Institute’s Enterprise Vocabulary Services (NCI EVS) at: http://www.cancer.gov/cancertopics/cancerlibrary/terminologyresources/cdisc.

Although the examples in CDISC data standards try to appear plausible, including using controlled terminology where available, they should not be regarded as a definitive source for controlled terminology. Some codelists and/or values applicable to biomedical concepts and data elements in a document may still be in development at the time of publication. Some examples may use values that appear to be controlled terminology, but which are actually generic or "best guess" placeholders. Readers should consult the current CDISC Controlled Terminology (available at the link above) as the ultimate authority for correct controlled terminology codelists and values.

Concept Maps

CDISC often uses concept maps to explain clinical processes and biomedical concepts. Concept maps, also sometimes called mind maps, are diagrams which include “bubbles” representing concepts/ideas/things and labeled arrows that represent the relationships between the concepts/ideas/things. They are generally easier to draw and more accessible than more formal modeling diagrams, such as Unified Modeling Language (UML) diagrams.
