Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Salon staff will direct their clients aged 45 years or older to a QR code which opens the study website. The decision to engage with the QR code and study website is entirely at the discretion of the potential participant. Intervention participants will be given online and printed generic women’s health advice and targeted cardiovascular (CV) risk materials designed specifically for this study at baseline comprising:
• Information about cardiovascular disease risk factors in women and the importance of a formal CV risk assessment and specific advice to book a Heart Health Check with their general practitioner. The materials will take approximately 5 minutes to read through.
• A letter for their general practitioner that promotes a formal Heart Health Check using the Medicare item number if appropriate.
The study will conducted in each salon until 27 participants have been recruited or 12 months from recruitment start date has passed (whichever occurs first).
After participants have consented and scrolled through the study materials, they will progress through the website to view a health questionnaire. Participants that complete the questionnaire will have viewed the study materials.

Comparator / control treatment
Salon staff will direct their clients aged 45 years or older to a QR code which opens the study website. The decision to engage with the QR code and study website is entirely at the discretion of the potential participant. Control participants will be provided with online and printed information sheet with general women’s health advice that is not specific to CV disease. The information sheet was designed specifically for this study. This will include national recommended breast screening safe alcohol intake levels and promotion of an active lifestyle and mental health. It will not mention the Heart Health Check. The materials will take approximately 2 minutes to read through.
After participants have consented and scrolled through the study materials, they will progress through the website to view a health questionnaire. Participants that complete the questionnaire will have viewed the study materials.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This study is a double-blind cluster randomised controlled trial where hair salons will be randomised to either the intervention or control arm. The web-based randomisation system will conceal the randomisation allocated to the salon. Study participants will thus be blinded to salon allocation and participant allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Enrolled salons will be allocated using a computer-generated randomisation algorithm 1:1 to intervention or control, stratified by salon SEIFA score. The allocation sequence will be generated by the system.
Masking / blinding

Statistical methods / analysis
Statistical Power
The sample size of 60 groups (salons) per randomisation strategy with 27 participants per group will provide 80% power (2 alpha=0.05) with an intra-class correlation of 0.1 to detect a 5% absolute difference in the primary outcome between randomised groups. This assumes a 5% background rate of Heart Health Check uptake in the control group, and a 5% absolute increase in women screened with the intervention.

Statistical Analysis
The primary intention-to-treat analyses will use a hierarchical log-binomial regression model with salon as a cluster random effect to estimate relative risks and 95% confidence intervals. Pre-specified subgroup analyses will assess effects by SEIFA decile (at a cluster level) and age and whether or not English is the first language (at an individual level). Imputation for missing data is not anticipated to be required for data linkage outcomes but may be done for self-reported data if significant missing data identified during the blind review.
