The evaluation of hypoglycemic events using a threshold of < 3.1 mmol/L separated for each period (Table 7) resulted in the following: in period 1 the proportion of patients with overall hypoglycemia was 18.3 % during treatment with insulin glargine and 15.2 % during treatment with NPH insulin (OR = 1.24; 95 % CI, 0.70 – 2.21). Here, INS is linked to Hypoglycemia.
