Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Prospective urn randomisation using a (2,1) sdchedule was used. A container with two coloured paper clips was prepared. One clip was blindly withdrawn and its corresponding treated noted on a folded piece of paper in an opaque nevelope which wa then sealed. This was repeated until 20 envelopes are created.
Masking / blinding
