Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children will randomly allocated in a 1:1 ratio to "Vit D" and "Placebo" treatments. Treatment allocation will stratified by gender.
Numbered containers with central randomisation by computer with code held by one designated person not involved with any other aspects of the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation used permuted blocks to maintain treatment balance over time, and blocks will be a random mixture of sizes to assist allocation concealment
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The project aims to show that oral vitamin D supplementation will improve the severity of childhood atopic dermatitis (eczema). We will compare the severity of disease in children with moderate-severe atopic dermatitis after 3 months of daily Vitamin D therapy or placebo, using randomised double blind placebo controlled methodology.
We propose that the severity of moderate and moderate-severe atopic dermatitis will be significantly decreased by oral Vitamin D therapy. We aim to show that in these children, following 3 months of daily vitamin D3 at 1000IU, there will be a significant decrease in their disease severity and decreased use of topical corticosteroids. We aim to demonstrate a significant improvement in the quality of life for these children, as measured by a validated quality of life questionnaire.
