I undersøgelserne målte man niveauerne for glykosyleret hæmoglobin (HbA1c), der viser, hvor godt blodets glukose holdes under kontrol, og glukoseniveauerne i fastende tilstand (målt mindst otte timer efter et måltid).
The studies measured the level of a substance in the blood called ‘ glycosylated haemoglobin’ (HbA1c), which gives an indication of how well the blood glucose is controlled, and ‘ fasting’ blood glucose levels (measured at least eight hours after eating).
