Table 3 Uptake, retention and weight loss across breast cancer risk categories in the two studies

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 programme

Study-2 Women informed of their breast cancer risk part way through the weight loss programme
