Overall conclusions • Improving metabolic control usually results in an increase in hypoglycaemia in patients with type 1 and type 2 diabetes • Insulin detemir results in a risk reduction of 5–55% for hypoglycaemia compared with NPH insulin in patients with type 1 and type 2 diabetes • Lower within-person variability of insulin detemir is associated with reduced risk of hypoglycaemia
