Area Under the Curves (AUC)

type 2 diabetes mellitus (T2DM)
Morbus value (M value)
Delta ratio of IGI
AUC ratio of IGI
Concerning diabetic nutritional therapy, Calorie Restriction (CR) and Low Carbohydrate Diet (LCD) have been on discussion. Authors continue clinical research related to CR, LCD, Morbus(M) value and insulin secretion.
Subjects and Methods
Subjects were 42 patients (63.4 years on average) with type 2 diabetes mellitus (T2DM) with its immunoreactive insulin (IRI) =<5μU/mL. Methods included CR breakfast with carbohydrate 70g (Carbo70), Insulinogenic Index (IGI) calculation and daily profile of blood glucose.
Subjects showed median data; M value 207, HOMA-R 1.0, Delta Ratio of IGI for Carbo70 is 0.12 [0.08–0.22], Area under the Curves (AUC) Ratio of IGI-Carbo70 is 3.0 [2.2-4.8]. Divided into 3 groups due to HbA1c, median glucose and M value was 133mg/dL, 227 mg/dL, 345mg/dL and 15.8, 207, 587, respectively. Delta and AUC Ratio of IGI-Carbo70 in 3 groups were 0.17, 0.10, 0.10and5.2, 2.9, 1.9, respectively. There were significant correlations between M value and Delta ratio / AUC ratio, in which the latter has higher degree of significance.
Discussion and Conclusion
Among 3 groups, the distribution was overlapped in Delta-IGI, and was rather divided in AUC-IGI. Consequently, the latter method seems to be rather superior. These results would be the fundamental data, and further development of research is expected.
