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. For instructions on abstracting interventions, refer to Abstracting Interventions.

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:
