In the first months following diagnosis, type 1 diabetes patients frequently experience a transient period of partial remission during which glycemic control can be achieved easily with reduced, or even suspended, insulin requirements. Over the past years, different criteria have been used in the literature to define this period, rendering it sometimes difficult to compare study results. In 2009, Mortensen et al.  proposed a new definition of the remission phase: the IDAA1C (Insulin Dose-Adjusted A1C = HbA1C + 4 x insulin doses/day/kg), with an IDAA1C ≤9 indicating that the patient is in remission phase. Though this formula is currently the most widely used in the literature, some authors criticize that it integrates the «insulin doses» parameter, as it may be influenced by several confounding factors.
