Randomisation, blinding and allocation
RECRUITMENT, BLIND
A study statistician independent of recruitment, intervention delivery and data collection will perform block randomisation using a computer-generated random number sequence in blocks of size 6 (using command RALLOC in STATA V.16, StataCorp, College Station, USA). Allocations will be prepared in sealed opaque envelopes by an independent study administrator and will not be revealed to participants until completion of baseline data collection. It will not be possible to blind the participant nor study researchers involved in intervention delivery to the allocated intervention group; however, data collection and analysis will be carried out by investigators blinded to treatment allocation.
