Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Treatments were allocated by writing 1,2 placebo on slips of paper, the participant numbers were on slips of paper. Allocation was made by drawing alternate numbers and names from separate containers. The bottles of lotion were labelled with the participants number by an independent researcher
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Treatments were allocated by writing 1,2 placebo on slips of paper, the participant numbers were on slips of paper. Allocation was made by drawing alternate numbers and names from separate containers.

Summary
Brief summary
The study design was a randomised, controlled trial. Repeated measures were taken at baseline, 3 points during treatment, and after a wash-out period at the end of the trial. The participants and the person doing the cognitive testing and data analysis were blinded to the treatment allocation, and the staff administering the treatment were blinded as to which of the treatments was the active. The trial will be carried out in parallel groups, with staggered starting times to allow adequate time for the cognitive testing.
