aThe absolute number and percentage are shown for categorical variables and the mean (SD) for continuous variables
bRead horizontally; No. and percentage follow-up are calculated based on year of surgery, e.g.: patients with surgery in 2017 could have a recorded follow-up at 3-years, but are not included for year 4 or 5
