Allocation concealment and implementation
Due to the nature of the intervention, participants could not be blinded to treatment allocation. The details of sequence generation and group allocation were unavailable to research team members bar one unblinded research assistant. The unblinded research team member that created the randomisation sequence had no contact with participants and was not involved with data collection or analysis. The unblinded research assistant initiated the treatment allocation sequence using REDCap and assigned participants to the intervention or control groups.
