From: Breast cancer risk status influences uptake, retention and efficacy of a weight loss programme amongst breast cancer screening attendees: two randomised controlled feasibility trials

 Study-1: Women informed of their breast cancer risk prior to invite to the weight loss programmeStudy-2: Women informed of their breast cancer risk part way through the weight loss programme
