Compared with controls, patients in the intervention group had
a comparable cumulative incidence rate for arm lymphoedema
defined as an increase of 200 mL or more 12 months after
surgery (18 (24%) in intervention group v 15 (19%) in control
group; odds ratio 1.3, 95% confidence interval 0.6 to 2.9;
P=0.45). Both groups also had a comparable cumulative
incidence for arm lymphoedema at three and six months after
surgery
