Home / Standards / Foundational / Study Data Tabulation Model Implementation Guide (SDTMIG)

Where the SDTM provides a standard model for organizing and formatting data for human and animal studies, the SDTMIG is intended to guide the organization, structure, and format of standard clinical trial tabulation datasets. It was developed to support data submitted to a regulatory authority, such as the US Food and Drug Administration (FDA), but is not restricted to use in regulated submissions. SDTM is one of the required standards that sponsors must use as specified in the FDA’s Data Standards Catalog (see section II.C) for NDA, ANDA, and certain BLA submissions effective December 2016. For more information, please visit the Guidance on Standardized Data.


Release Date: 20 Nov 2018

Version 3.3 of the Study Data Tabulation Model Implementation Guide for Human Clinical Trials (SDTMIG) is available in HTML format, which can be viewed in a browser.

Release Date: 16 Jan 2012

CDISC has released the final version 1.0 of the MSG Package, which was originally released for public comment from 2010-05-14 to 2010-06-07. During that review period, over 570 comments were received, which needed to be resolved before this final package could be released. An appendix to SDTMIG v3.1.2 is included with the package to familiarize users with the SDTM submission components. Additionally, a sample electronic submission is included, which contains an annotated CRF, submission datasets compliant with the SDTMIG v3.1.2, a Define.xml file describing the structure and content of the submitted datasets, a stylesheet for visualizing the define.xml in a user-friendly way, and an optional reviewers’ guide.

SDTMIG v3.2 Conformance Rules v1.0

Release Date: 27 Jan 2017

The SDTMIG v3.2 details the structure and conventions for compliant SDTM domains. The majority of the SDTMIG v3.2 is published in a data definition table format, which allows the information to be used programmatically. Business and conformance rules (e.g., assumptions and examples), however, are expressed outside of the data definition tables, making them difficult to identify and program.

SDTMIG v3.2 Conformance Rules v1.0 aim to identify all conformance rules and case logic from the SDTM and SDTMIG, classifying and codifying them in a form that supports SDTM quality processes and tool development. 

The Conformance Rules team has created a user guide that provides information on the structure of the rules and conventions for rules content.
