Long term follow-ups will be performed at 2, 5 and 10 years Due to lack of studies published within this field: clinical relevant differences as well as changes within groups and SD are difficult to estimate. Our sample size calculations are based on primary outcome iHOT 33 at 1 year: estimated effect-size to 0.6 and a power of 90, will give 60 in each group, and with expected 15% dropout will give 138 patients in total. Electronic randomization lists will be generated, and estimations of inclusion rates per site are included. Statistical analysis procedures will be published and analysis performed prior to opening the group allocation when all patients are included and followed through to the 1 year follow-up (main outcome).
