An Event is a group of Forms used in your Study. An Event may or may not correspond to a real-world visit. There are two main types of Events:
- Visit-Based Events
- Common Events
For information on Event Statuses and Attributes, refer to Status Icons.
Visit-Based Events
Most Events in a clinical trial are Visit-Based Events, such as Week 2, Week 6, or Monthly Follow-up.
- These visits are scheduled relative to the baseline (for example, Week 2 occurs two weeks after baseline, Week 6 occurs six weeks after baseline).
- The visit schedule is defined in the Study protocol.
- Each visit includes a specific set of Forms to be collected.
When you review the Visits section, the system automatically opens the earliest visit that is not complete. Incomplete visits display with a blue background.
A visit is considered complete when it has one of the following statuses: Complete, Skipped, Stopped, Removed, or Archived.

Common Events
Some Events are not tied to a visit date and occur outside of the regular schedule. Examples include:
- Adverse Events (AEs)
- Concomitant Medications (ConMeds)
- Early Termination
Common Events are used to collect information independent of visit timing.
They can be configured as:
- Repeating Events – for data that may occur multiple times per Participant (e.g., AEs, ConMeds).
- Non-Repeating Events – for data that can occur only once per Participant (e.g., Early Termination).

ℹ️ Note: The form that was opened most recently is indicated by the yellow background.
Event Types and Icons
| Icon | Event Type | Description | Example(s) |
|---|---|---|---|
![]() | Visit | An event that is associated with a visit date. The event can be repeating or non-repeating. | Week 2 Visit (non-repeating); Monthly Follow-Up for Disease-Free Survival (repeating) |
![]() | Common | An event that is not necessarily associated with a visit date. | Early Withdrawal or Termination (non-repeating); Adverse Events (repeating) |
![]() | Repeating | An event that repeats in your study, either a known or unknown, number of times. This icon will appear adjacent to one of the previous two when an event is a repeating event. | Concomitant Medications |
Scheduling an Event
Once a Participant has been added, you can schedule Events.
You can schedule Events from:
- The Participant Matrix
- The Participant Details screen
- The Tasks menu
For more information, refer to Scheduling and Editing Events.
