Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The group allocation will be provided via the computer system (REDCap) once the participant has been enrolled, and all participant data have been entered, and the researcher has indicated that written informed consent has been provided. REDCap will provide the group allocation upon randomisation.
The trial researchers randomising the participants will not have access to the randomisation list.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation sequence will be a computer-generated random number based on block randomisation with varying block length ranging from 4 to 8. One stratum will be applied, i.e., participants’ gender. The randomisation sequence will be generated via the online platform randomizer.org.
Masking / blinding

Statistical methods / analysis
The primary outcome is feasibility, and it will be reported descriptively as absolute and relative frequencies, means and standard deviations or median and ranges depending on the data distribution.
Secondary continuous outcomes will be analysed using Linear Mix Methods Model for between subject across time effects between groups, in addition to a between groups analysis using univariate analysis (ANCOVA), which models the posttreatment outcome as a function of treatment group (classified factor), and the respective baseline value (linear covariate). Efficacy estimates will be reported as group differences with 95% confidence intervals, and effect sizes.
