INS and Hyperglycemia: There were no statistically significant differences between the acarbose group and insulin monotherapy group in the 24 h MBG, the standard deviation (SD) of the 24 h MBG, the percentage time duration of hyperglycemia (glucose > 10 mmol/L), hypoglycemia (glucose < 3.9 mmol/L), the number of hyperglycemia (glucose > 10 mmol/L) episodes, and the number of hypoglycemia excursion (glucose < 3.9 mmol/L) episodes (see Table 2).
