Table 5 Changes in anthropometric measures and blood pressure from baseline to 3 months by randomisation group

From: Breast cancer risk reduction - is it feasible to initiate a randomised controlled trial of a lifestyle intervention programme (ActWell) within a national breast screening programme?
