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.
TA Specifications show how to modify TAUG examples for various versions of the SDTM and SDTMIG. These specifications assist the FDA and the Japanese PMDA with testing to enable support of the standards and inclusion in their respective Technical Conformance Guides.1,2
The specifications comprise five worksheets in an Excel workbook:
- Read Me – Information on how to read the other worksheets
- Summary – Table of Contents for the TAUG annotated with examples and the domains and variables they use
- Known Issues – A list of modeling issues noted in the TAUG
- Domains – Domains used and their status in different versions of the SDTMIG
- Variables – Variables used and their status in different versions of the SDTM
