Trials

This is a dual-bound connection with a directional connect rule. The same junction links a persona to a trial and a trial to a persona.

Directional connect rule: New links can only be created from the persona page. The trial page shows existing persona connections but does not allow adding new ones directly.

Why it matters

• persona work is used to reason about a specific study’s target population
• reviewers need to understand which trial a persona view applies to
• persona-specific engagement questionnaires and feedback are reviewed from the persona perspective

This relationship supports:

• personas generated from trial context
• engagement questionnaires and feedback reviewed from the persona perspective

From each side

• Use Personas when the team is refining the participant profile and reviewing which trials it informs.
• Use Trials when the team is working from the study outward and reviewing trial-specific persona connections.
