Abstracting Groups and Cohorts
...

Group/cohort information pertains to Complete non-interventional trials only. In non-interventional studies, cohorts are groups of individuals, initially defined and composed, with common characteristics (e.g., condition, birth year), who are examined or traced over a given time period.
When adding groups to a trial, you assign to them the interventions currently abstracted for the trial.

Before you begin abstracting or validating any trial, be sure you check it out first. Otherwise you will not be able to modify any trial data. |
The following rules apply to each trial:
There must be at least one group/cohort that implies that the entire study subject population receives the same intervention.
The number of groups/cohorts added to the trial must coincide with the number indicated in the trial’s Design Details. See Abstracting Non-Interventional Trial Design Details .
- Every group/cohort must have at least one assigned intervention.
- Every intervention must be assigned to at least one group/cohort.
- A trial must have only one group with the same combination of description and associated intervention.
Trials can have multiple group/cohort records. Each record displays the following group information:
| Field | Definition |
|---|---|
Label | Short name used to identify the group |
Description | Explanation of the nature of the study group (e.g., those with a condition and those without a condition; those with an exposure and those without an exposure). |
Assigned Interventions | Intervention assigned to a given group |
...
Adding Groups
You can add one or more groups to a trial according to the number specified in the trial’s design details. See Abstracting Non-Interventional Trial Design Details .
How to Add Groups
...
Field | Instruction/Description |
|---|---|
Label* | Enter the descriptive name of the group. |
Description* | Enter a brief description of the group. |
Assignment | Select the check box(s) in the column for the intervention(s) assigned to the current group. |

How to Delete Groups
- Search for the trial of interest. In the search results, click the NCI Trial Identifier link for that trial.
- On the Scientific Data menu, click Groups/Cohorts. The Groups page appears.
- In the Delete column, select the check box for the appropriate record(s), and then click Delete.
- To delete all groups, click Select All, and then click Delete.

Code | Characters, or phrase used to identify the sub-group |
Description | Stratification criteria |
