What is SDTM mapping?

One of the most challenging programming problems in a clinical trial involves SDTM mapping. That is mapping datasets from a non-CDISC structure to the CDISC SDTM structure.

What is SDTM Implementation Guide?

A Study Data Tabulation Model Implementation Guide (SDTMIG) is developed in reference to a specific SDTM model. However, the SDTM is cumulative – each new release builds on the previous model. Therefore, the models are backward compatible. For example, SDTMIG-AP v1.

What is SDTM format?

Study Data Tabulation Model (SDTM) defines a standard structure for human clinical trial (study) data tabulations and for non-clinical study data tabulations, that are to be submitted as part of a product application, to a regulatory authority such as the United States Food and Drug Administration (FDA).

What is the difference between SDTM and ADaM?

ADaM goes hand in hand with SDTM They might have different functions, but ADaM ties in super-closely with the Study Data Tabulation Model (SDTM). While SDTM is used to create and map collected data from raw sources, ADaM is all about creating data that’s ready for analysis. SDTM is ALWAYS the source of the ADaM data.

What is epoch in SDTM?

3, EPOCH is derived in a consistent way with the other SDTM domains. Historically, in SDTMIG v3. 2 and earlier, guidance was: “When EPOCH is populated for disposition events (records with DSCAT = DISPOSITION EVENT), EPOCH is the name of the Epoch for the disposition event described in the record.

What is metadata in SDTM?

metadata: Domain Class, Domain Prefix, Variable Name, Variable Label, Type, Role and Core. The main sources for the additional information are the SDTM model and the SDTM IG, and text held within the eSHARE file which corresponds to text in the IG (see Table 4, CDISC Notes).

What is SE domain in SDTM?

SE is a special purpose SDTM domain containing one record per subject per study element. Its purpose is to describe the study elements that a subject participated in during the study and the dates associated with those elements.

What is the difference between SDTM and Sdtmig?

The SDTM is a metadata model and SDTMIG domains classified as Interventions, Events, Findings, or Findings About are instantiations of an SDTM general observation class. Users who become familiar with the SDTM root variable definitions understand a variable’s meaning in SDTMIG domains.

What are the core variables in SDTM?

Core variables are a measure of compliance with the specific SDTM-IG domain model. The value of a core variable shows the importance of the variable to the overall domain structure. Variables are divided into 3 categories: Required variables are needed to identify a data record, e.g STUDYID, and USUBJID.

What is baseline flag in SDTM?

The Study Data Tabulation Model (SDTM) baseline flag should be used on team consent; otherwise it may be necessary to ask for appropriate baseline definition. Baseline definition can be a specific visit or the last non missing result prior to first dose.

What are the SDTM data sets?

SDTM (Study Data Tabulation Model) defines a standard structure for human clinical trial (study) data tabulations and for nonclinical study data tabulations that are to be submitted as part of a product application to a regulatory authority such as the United States Food and Drug Administration (FDA).
