The primary outcome was proportion of participants developing lymphoedema (defined by RAVI > 10% from pre‐operative measurement) by 24‐months post‐randomisation in each arm as assessed by time to lymphoedema. Arm volume was measured at baseline, 1, 3, 6, 9 and 12 months then 6 monthly thereafter to 2 years, followed by annual measurements to 5 years after trial entry using a perometer.
