Dynamic Groups

Dynamic Groups extend the Subject Group Class concept by linking group membership to events on the Subject Matrix. Subjects assigned to a Dynamic Group Class will only see the events belonging to their assigned class — all other events are hidden.

Overview

A Dynamic Group Class is similar to a Subject Group Class, but instead of static categories, it maps to Events from the Subject Matrix.

When Dynamic Groups are enabled:

• Each subject is assigned to one Dynamic Group Class
• Only the events belonging to that class appear on the subject's event matrix
• Events in other Dynamic Group Classes are hidden for that subject

This is particularly useful in adaptive trials or studies with multiple visit schedules depending on cohort or arm assignment.

Enabling Dynamic Groups

Toggle the Enable Dynamic Group Class switch at the top of the page to turn the feature on or off for the study.

State	Behavior
Off (default)	All events are visible for all subjects
On	Each subject only sees events assigned to their Dynamic Group Class

How Dynamic Groups Work

1. Create a Dynamic Group Class and assign specific events to each class
2. When a subject is enrolled, assign them to a Dynamic Group Class
3. The subject's event matrix will only display events from their assigned class

Assignment Methods

Subjects can be assigned to a Dynamic Group Class via:

Method	Description
Manual	A study coordinator updates the subject's group class when editing the subject profile
API	An API call (e.g., from a Randomization system) assigns the group automatically
