Patient & public involvement (PPI)
Patients are at the heart of our research. Learn how your involvement shapes the FREEDOM trial.
Designed with patients, not just for them
The National Institute for Health and Care Research (NIHR) defines public involvement in research as research being carried out ‘with’ or ‘by’ members of the public rather than ‘to’, ‘about’ or ‘for’ them.
This has been central to the design of the FREEDOM trial.
