ISRCTN registry
We are experiencing some intermittent email issues.
If you have requested an update to your record using the 'Update your record' or 'Report your results' forms, and AFTER 1 WEEK you have not been contacted by one of the ISRCTN editorial staff by email to say that your record has been updated, please try to send the update again using the forms, or send your update via email. (Please wait 1 week as we do not process update requests immediately, there is a backlog)
The ISRCTN registry is a primary clinical study registry recognised by the World Health Organisation (WHO) and the International Committee of Medical Journal Editors (ICMJE) that accepts all clinical research studies (whether proposed, ongoing or completed), providing content validation and curation and the unique identification number necessary for publication. All study records in the database are freely accessible and searchable.
ISRCTN supports transparency in clinical research, helps reduce selective reporting of results and ensures an unbiased and complete evidence base.
The registry aims to include all interventional and non-interventional clinical studies that prospectively involve UK participants and evaluate biomedical or health-related outcomes.
Studies conducted outside the UK or considered to be non-clinical studies (e.g. public health studies) can be registered on ISRCTN.
Studies should ideally be registered prospectively (before recruitment starts). ISRCTN also accepts studies registered retrospectively once they are underway or after completion.
