1Observation Class

Tabulation Dataset Generation

Specifies the SDTM class for the domain. 

2Domain

Tabulation Dataset Generation

Specifies the 2-letter domain code.

3Data Collection ScenarioData Collection Field Implementation

Indicates when a collection field should be used based on a specific context. Values in this column should be used with values in TIG Core to determine when a field should be present on a CRF. Values in this column are:

  • A short description of the context in which the collection field should be present.
  • N/A for when no specific context for use applies to the collection field.

4

Implementation Options 

Data Collection Field Implementation

Indicates Specifies how to read/implement.

When this column contains "Horizontal-Generic," a sampling of the CDASHIG metadata is provided as a template for the metadata of the CRF in a denormalized structure.

Is this applicable to TIG specifications? 

5Order NumberData Collection Field ImplementationProvides a suggested order of fields to be displayed on a CRF. 
6Data Collection Variable

Tabulation Dataset Generation

Provides the data collection variable name. 

7Data Collection Variable Label Tabulation Dataset GenerationProvides the data collection variable label.   
8DRAFT CDASHIG DefinitionCRF and System DesignProvides a draft definition of the CDASHIG variable for understanding and proper usage
9Question Text

CRF and System Design

Provides full sentence/question forms to prompt for data. Values in this column are: 

  • Without text in brackets or parentheses to be used as-is.
  • With text in brackets to be replaced with protocol-specified verbiage.
  • With text in parentheses indicating optional text.
  • With text separated with a forward slash indicating optional wording.


  1. In Findings domains, values from the relevant CDISC CT lists must also be used to create appropriate Question Text, Prompts, and/or variable names. For example, if the question is about the subject's height, incorporate the value of "Height" from the VSTEST codelist as the prompt on the CRF, and incorporate "HEIGHT" from VSTESTCD in the variable name.

10

Prompt 

CRF and System Design

Provides short phrases, suitable as column headers, to prompt for data. Values in this column are phrases:

  • Without text in brackets or parentheses to be used as-is
  • With text in brackets to be replaced with protocol-specified verbiage.
  • With text in parentheses indicating optional text.
  • With text with NULL indicating the prompt is not required on a CRF screen/page if not needed.
11Data Type 

Tabulation Dataset Generation

Specifies the data type of the variable. Values for in this column are:

  • Num for numeric data
  • Char for character or alphanumeric date

12

TIG Core 

CRF and System Design

Specifies expectations for the inclusion of the field on the CRF. Values in this column should be used with values in Data Collection Scenario column to determine when a field should be present on the CRF. Values in this column are:

  • HR for fields that are Highly Recommended and should always be on the CRF.
  • R/C for fields that are Recommended/Conditional and should be on the CRF based on in certain conditions.
  • O for fields that are Optional and should be on the CRF when needed to support data collection when needed.
13Case Report Form Completion InstructionsData Collection Field Implementation

Provides recommended example instructions to support authoring of study-level documentation for instructing sites how to complete CRF fields.   










14Tabulation Target 

Tabulation Dataset Generation

This column provides the suggested mapping to the tabulation dataset variable. Values in this column are:

  • The name of the tabulation dataset variable to which the value of the data collection variable will be mapped.
  • N/A for when no direct mapping to a tabulation dataset variable is available.
  • SUPP–.QNAM for when a value represented in the field will be mapped to as a Supplemental Qualifier.
15Mapping Instructions

Tabulation Dataset Generation

Provides information on the suggested mapping of the collection variable to the tabulation variable

16Controlled Terminology Codelist Name 

CRF and System Design

Specifies controlled terminology applicable to the field. Values in this column are:

  • Names of controlled terminology codelists with allowable terms to populate the variable. Codelist names are specified in paratheses. Multiple codelist names indicate the variable is subject to one or more of the codelists.
17Subset Controlled Terminology/CDASH Codelist Name:CRF and System Design

This column contains the CDISC CT or CDASH subset codelist name that may be used for that specific variable (e.g., EXDOSFRM). 

Link back to CT section.

Implementation Notes 

CRF and System Design

Provides additional context for implementation of CRF data collection fields and mapping to tabulation datasets content may include:

  • Rationale
  • Implementation instructions
  • A description of condition(s) when the value of TIG CORE is R/C
