Nutrition Therapeutic Area User Guide v1.0

Published Date:

Version 1.0 of the Therapeutic Area User Guide for Nutrition focuses on infant nutrition, food and fluid intake, stool sampling, and questionnaires (specific to clinical studies in nutrition), and includes concepts for adult and pediatric populations. TAUG-Nutrition v1.0 was developed under the CDISC Standards Development Process and describes the most common biomedical concepts relevant to nutritional studies, and the necessary metadata to represent such data consistently with Terminology, CDASH and SDTM.

TA Standards extend the Foundational Standards to represent data that pertain to specific indications within disease areas. CDISC Standards specify how to structure the data; they do not specify what data should be collected or how to conduct clinical trials, assessments or endpoints.

Public Review Comments

CDISC posts Public Review comments and resolutions to ensure transparency and show implementers how comments were addressed in the standard development process.
