I undersøgelserne sammenlignede man over en periode på seks måneder Actrapid med en human insulinanalog (insulin aspart) ved at måle niveauet for et stof i blodet kaldet glykosyleret hæmoglobin (HbA1c), der indicerer, hvor godt blodets glukose holdes under kontrol.
The studies compared Actrapid to a human insulin analogue (insulin aspart) over six months by measuring the level of a substance in the blood called glycosylated haemoglobin (HbA1c), which gives an indication of how well the blood glucose is controlled.
