INS and Hypoglycemia: We classified 76 (59%) patients with an HbA1c > 7.5% (58,2 mmol/l) as patients with “HIGH-A1c” and 53 (41%) patients with an HbA1c ≤ 7.5% (58,2 mmol/l) as patients with “LOW-A1c.” Groups did not differ with regard to insulin therapy [χ2(1) = 0.362; p = 0.834], to mean age, marital status of the parents, diabetes in other family members, frequency of hypoglycemia and microalbuminuria (see Table 1).
