NICE FIT is registered on the UK Clinical Trials Gateway. This helps give people the confidence to join clinical trials, by providing useful information about how trials work – while helping link them to researchers running trials they might be interested in. It also helps researchers find suitable people for the trials they’re running.


NICE FIT is listed on the ISRCTN registry. This primary clinical trial registry is recognised by WHO and ICMJE.

ISRCTN supports transparency in clinical research, helps reduce selective reporting of results and ensures an unbiased and complete evidence base.

All study records in the database are freely accessible and searchable.


The NICE FIT study was granted approval to join the NIHR Clinical Research Network portfolio, an exclusive collection of high quality research studies.
