BARCODE1 pilot study recruitment. Percentages relate to the proportion of invitations to the study. *Saliva samples from four participants were received after 15 April 2018, which was the cut‐off date for DNA extraction in the pilot study. These participants will have DNA extracted and analysed in the main BARCODE1 study. One saliva sample did not yield sufficient DNA at extraction and a new saliva sample was requested. This participant will also be added to the main BARCODE1 study.
