# Self reported episodes of hypoglycaemia, with 4 levels of severity (level 1 = hypoglycaemia cured with the intake of for example fluids containing sugar, no help from other required, level 2 = hypoglycaemia cured with the intake of for example fluids containing sugar, help from others required, level 3 = hypoglycaemia with help from doctor required (no hospital admission), level 4 = hypoglycaemia resulting in hospital admission), then added with severity weights (level 1 × 1, level 2 × 2, level 3 × 3, level 4 × 4) and finally divided in 3 groups 0, 1-11 and 12 to max ## Self reported on a scale from 1 to 5 (1 = not at all, 5 = very much), recoded to 2 levels (> and < than 2.5 due to imputed values having values with decimals)
