  1. Differences analysed using Mann–Whitney U-test for continuous variables and Fishers exact test för frequencies. Results are expressed as mean with standard deviation (SD) and median with range.
  2. HbA1c glycated haemoglobin (*closest to the time of examination, **over time from onset). Body mass index (kg/m2) (***corrected for age according to WHO).
  3. Significance level < 0.05.
