Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be done in the study database using the inbuilt randomisation module. Investigators will not have access to the randomisation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A statistician generated block randomisation schedule, using a block size of four

Statistical methods / analysis
Based on a minimum clinically important difference (MCID) of 3.4 and standard deviation (SD) of 4.8 for the change in POEM score, each treatment group would require 32 participants. Accounting for an assumed dropout rate of 20% in such a community-based study, 40 participants would be required per arm (80 total) having 80% power at 5% two-sided alpha.

Summary
Brief summary
This study will assess the efficacy of 3% Kanuka Oil cream in the treatment of eczema.
The study is designed as a single blind, randomised, vehicle controlled study. 80 participants will be recruited via pharmacies throughout New Zealand and will be randomised 1:1 to receive either 3% Kanuka Oil cream or vehicle control.
Participants will be recruited from community pharmacies by pharmacy staff. Pharmacy staff will be trained as investigators by a MRINZ investigator. The baseline visit will consist of screening, consent, demographics, eczema scoring, photo capture of a representative eczema lesion, randomisation and supply of study medication. Participants will be instructed to apply their treatment twice daily for six weeks.
Participants will complete a weekly electronic diary for five weeks. The electronic diaries will capture symptom scores, treatment compliance, and adverse events. A paper diary will be offered as a back-up if participants are unable to complete the electronic diary. The paper diary will be returned at the final study visit.
The participants will return to the pharmacy at the end of week six for a final study visit. The final visit will consist of eczema scoring, photo capture of a representative eczema lesion, treatment acceptability, adverse event collection, and concomitant medication collection.
A survey, two weeks after the final visit, will capture information about adverse events post study treatment.
The primary outcome for this study is improvement in patient reported symptoms at six weeks. Secondary outcomes include improvement in patient reported clinical signs, improvement in patient reported quality of life, and inter-rater validity of SCORAD (intensity section) between a blinded dermatologist and pharmacy investigators.
