    Document: Block randomisation with 1:1 allocation will be carried out according to a computer-generated sequence, and will be performed by one of the authors (AL) not involved in screening, patient recruitment, clinical care or data collection, using a software program PASS V.11 software (NCSS, Kaysville, Utah, USA).
