Design outcomes

Primary

Measure	Time frame
The total number of patients recruited in 6 months to the WHiTE 8 COPAL trial, which is routinely collected for the Oxford CTU on a monthly basis for all WHiTE trials. Data will be collated on an Excel spreadsheet for each trial centre on a monthly basis until 6 months in total.	—

Secondary

Measure	Time frame
1. Time taken to begin each intervention from centre activation, taken from Oxford CTU records at the time of interventions commencing at each trial centre 2. Feasibility of delivering both interventions, determined from a logbook of data collected by the CI at 6 months 3. Conversion rate to recruitment from the proportion of those screened to be eligible in each of the intervention groups, taken from Oxford CTU records on a monthly basis 4. Feedback on the trainee perspective of the TPI role via a survey completed by the TPI in the last 2 weeks of their role 5. Time needed to conduct the 1:1 educational training session for TPIs, determined from a logbook of data collected by the CI at 6 months 6. Required time and method of additional contact for peer support of the TPIs, determined from a logbook of data collected by the CI at 6 months	—
