Randomization and masking
Allocation to condition occurred once the participant was included in the trial. An independent lab-technician not related to the current investigation conducted a simple randomization of participants by means of lottery draw from slips in a container (1:1 ratio). Both study investigators and participants were blinded to treatment allocation. The code for revealing condition allocation was unlocked in April 2022, after the 6-months follow-up data collection came to an end and after statistical analyses were conducted.
