This unit is one of two centres of collection for this trial
The study was organised jointly by Queen Mary University of London and Barts and The London NHS Trust along with the MRC Epidemiology Unit.
The Trial has successfully collected data from its first volunteers in August 2010. These were collected by the MRC Epidemiology Unit. Since then all the data collected at both centres has been assembled in the Unit, cleaned, validated and a full complete master database has now been created (October 2013).
