Undersøgelser af natlig hypoglykæmi hos patienter med type 1 diabetes viste en betydeligt lavere risiko for mindre natlig hypoglykæmi (i stand til at behandle sig selv og bekræftet ved kapillærblodglukose under 2, 8 mmol/ l eller 3, 1 mmol/ l end med NPH- insulin), hvorimod der ikke blev observeret en forskel ved type 2 diabetes.
Analyses of nocturnal hypoglycaemia in patients with type 1 diabetes showed a significantly lower risk of minor nocturnal hypoglycaemia (able to self-treat and confirmed by capillary blood glucose less than 2.8 mmol/ L or 3.1 mmol/ L if expressed as plasma glucose) than with NPH insulin, whereas no difference was seen in type 2 diabetes.
