Inside the case
Every participant completed the trial
All 47 randomized participants completed the study. Randomization through completion took place within one month, delivering a 100% completion rate for the randomized group.
A complete follow-up outcome
There were no early withdrawals and no participants lost to follow-up. Early expectation setting and continued communication accompanied high participant compliance and full study completion.
The challenge. Our response.
Keep 47 participants connected through a compact study.
The operational challenge was coordinating participation and maintaining contact across a group of 47, from randomization through completion within one month.
Coordinating a 47-participant study group
The challenge
Visit planning and clear expectations had to work across the availability of 47 participants within a compact study period.
How our team responds
We discuss the participation commitment early and coordinate scheduling with participants. This gives each person a clear understanding of the study expectations and the time involved.
Maintaining contact through completion
The challenge
Every participant needed continued engagement through the end of the trial.
How our team responds
Our team emphasized ongoing relationships and open communication throughout participation. All 47 randomized participants completed, with zero early withdrawals or losses to follow-up.
Study outcome
47 randomized. 47 completed. One month. Zero early withdrawals or losses to follow-up.
The participant experience
Every participant mattered, through the final visit.
Preparation before screening and consistent communication remained priorities throughout this one-month study. Our team built participant relationships and maintained an open line for questions. High compliance accompanied completion by all 47 randomized participants.
Set expectations before screening
We discuss the study commitment early, including what participation will require and whether candidates feel ready to meet those expectations. Pre-screening helps establish a shared understanding before the first screening visit.
Build a working relationship
Participants need a team they can talk to. We build relationships throughout the study and keep communication open so questions and practical concerns can be raised with the site.
Keep the focus on follow-through
Our participant engagement approach continues beyond randomization. We stay connected throughout participation to support retention and compliance with study requirements.
Practical participant support
Help with the journey.
Support through the study.
We provide transportation support when needed to help participants attend study visits. We also discuss scheduling concerns early and maintain open communication throughout participation, helping address the practical barriers that can make follow-through difficult.
The result
47 randomized. 47 completed. One month. Zero early withdrawals or losses to follow-up.
