STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Simple randomisation using by using procedures such as coin-tossing or dice-rolling Allocation was determined by the holder of the sequence who is situated off site Open-label(Masking Not Used)
