Class: AnalysisOutputCategorization

The AnalysisOutputCategorization class can be used to create sponsor-defined categorizations, where a categorization is a set of categories with a common topic. Defined categorizations are stored in the reporting event's analysisOutputCategorizations attribute. In its simplest form, a categorization is a list of categories, each of which is a label with an associated identifier value. However, it is possible to define 1 or more subcategorizations for any category. Each subcategorization is another instance of the AnalysisOutputCategorization class, with its own list of categories (each of which may again have subcategorizations).

ER Diagram: AnalysisOutputCategorization

The categories within any categorization (or subcategorization) may be used to categorize any analysis or output. Each analysis or output may be assigned to one or more categories by including the identifier value of the category in the categoryIds attribute of the analysis or output.

Example

In this example, the sponsor defined 2 categorizations, which are represented—with identifier values assigned for both categorizations and categories—in the reporting event's analysisOutputCategorizations attribute:

Lines 2-10:

Show the "Group of Analyses" categorization with 3 categories:

  • Population Description
  • Safety
  • Efficacy
Lines 12-19:

Show the "Estimand Analysis Type" categorization with 3 categories:

  • Primary Estimator
  • Sensitivity Analysis
  • Supplemental Analysis

YAML Example
analysisOutputCategorizations:
- id: Catn_01_Grp
  label: Group of Analyses
  categories:
  - id: Catn_01_Grp_1_Pop
    label: Population Description
  - id: Catn_01_Grp_2_Saf
    label: Safety
  - id: Catn_01_Grp_3_Eff
    label: Efficacy
- id: Catn_02_Est
  label: Estimand Analysis Type
  categories:
  - id: Catn_02_Est_1_Prim
    label: Primary Estimator
  - id: Catn_02_Est_2_Sens
    label: Sensitivity Analysis
  - id: Catn_02_Est_3_Supp
    label: Supplementary Analysis

These categorization and category definitions could be represented in tabular form as shown in the following table where:

  • Each instance of the AnalysisOutputCategory class is shown on a separate line, with values for the id and label attributes shown in the category_id and category_label columns, respectively.
  • Attribute values each instance of the AnalysisOutputCategorization class are represented on each of the rows for the categories in the categorization.

In the same reporting event, both analyses and outputs were categorized by specifying one or more of the defined category identifier values in the categoryIds attribute:
Lines 5, 18:

Show that both the "Summary of Subjects by Treatment" analysis and the "Summary of Demographics" output were categorized as "Population Description".

Lines 10-11:

Show that the "Comparison of Change in Clinical Characteristic X by Treatment" analysis was categorized as both "Efficacy" and "Primary Estimand".

Line 23:

Shows that the "Change in Clinical Characteristic X" output was categorized as "Efficacy".

YAML Example

- id: An01_05_SAF_Summ_ByTrt
  name: Summary of Subjects by Treatment
  categoryIds:
  - Catn_01_Grp_1_Pop

- id: An02_03_SAF_Summ_ByTrt

Example

In this example, the sponsor had a specific operational need to categorize analyses and outputs according to the class and type of data included in each analysis or output. They therefore defined a top-level "Data Class" categorization with a "Data Type" subcategorization for each of the data class categories. This categorization and its subcategorizations are represented—with identifier values assigned for both categorizations and categories—in the reporting event's analysisOutputCategorizations attribute.

The categorization and category names represented here are only examples of ways in which a sponsor might choose to categorize, and subcategorize, the analyses or outputs included in a reporting event. While the categorizations chosen for this example are similar to Study Data Tabulation Model (SDTM) general observation classes and domains, this does not imply that analyses or outputs should be categorized by data class or data type as shown here.

In these line captions, categorization labels are shown in bold and category labels are shown in italics.:

  • Data Class (categorization)
Lines 5-7:
    • Subject-level (category of "Data Class")
