Randomisation and blinding
RECRUITMENT, BLIND
The randomisation sequence was created prior to the commencement of participant recruitment and embedded within the REDCap database. The next allocation was concealed to the recruiter (the GP), and only revealed after a new participant record was created and the baseline questionnaire completed. Participants and GPs were not blinded to allocation after randomisation, however outcome assessors were blind to treatment allocation. Participants were randomised 1:1:1, stratified by GP practice.
