Using the ISRCTN registry to track transparency
The ISRCTN registry wants to encourage trialists to follow research openness and transparency recommendations. Registry records now display green badges to highlight prospective registration, regular updating of ongoing records and posting protocols, statistical analysis plans (SAPs), data links and results to the record. The BEEP trial is an example that has several of the green badges. Do you think this is useful? We are keen to know what you think! Please send your feedback to info@isrctn.com

Please note that the ISRCTN registration fee is changing from GBP226 to GBP250 on 1st July 2022.

ISRCTN registry

The ISRCTN registry is a primary clinical trial registry recognised by WHO and 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.

ISRCTN accepts all studies involving human subjects or populations with outcome measures assessing effects on human health and well-being, including studies in healthcare, social care, education, workplace safety and economic development. The registry welcomes submissions in English from any location. Studies should ideally be registered prospectively (before recruitment starts). ISRCTN also accepts studies registered retrospectively once they are underway or after completion.
