What type of information does the CSPRG hold for the purposes of the SIGGAR study?

The CSPRG holds personal information (such as name, full date of birth, NHS number) only for the 5,384 SIGGAR patients who were randomised on the SIGGAR trials and did not withdraw their consent (64 patients).

We hold only de-identified data for the 3036 patients who were eligible but not randomised and 734 patients who were not eligible).

Additionally, we also hold:

• clinical data including data on symptoms, endoscopy, pathology, radiology and bloods
• cancer and mortality data from NHS Digital for patients in the SIGGAR trials.

Also see details on the SOCCER study for which we are still collecting follow-up data.
