Analytical results showing the increase in power through a re-randomisation design for different ICC values. This graph shows the difference in power between an unadjusted analysis (ignoring patient-effects) and an adjusted analysis (accounting for patient-effects) for a re-randomisation design across different ICC values. There are 100 patients who are randomised once, and 50 patients who were randomised twice (200 overall observations), and the treatment effect is 0.40, with the within-patient standard deviation set to 1
