The published minimal clinically important difference for SF-36v2 physical function is 10 points, applicable to both adults and those aged 12–17. Baseline SF-36v2 PF data from 35 non-surgical patients with severe PE yielded a standard deviation of 27.4. A sample of 170 participants provides 90% power to detect a 15-point difference in SF-36v2 PF score using a conservative SD of 30. The primary outcome of RESTORE is change in SF-36v2 physical function score from baseline to 1 year. An SF-36v2 PF score of 80 or below is a trial inclusion criterion.
