Table 1 Guidance on target for assessment of glycemic control in patients with diabetes

From: Time in range: a new parameter to evaluate blood glucose control in patients with diabetes

 TIRTime in hypoglycemiaTime in hyperglycemia
T1DM and T2DM> 70% (70–180 mg/dL)< 4% below 70 mg/dL < 1% below 54 mg/dL< 25%
T1DM and T2DM “fragile”> 50% (70–180 mg/dL)< 1% below 70 mg/dL> 90% below 250 mg/dL
T1DM pregnancy> 70% (63–140 mg/dL)< 4% below 63 mg/dL< 25% above 140 mg/dL
Gestational DM and T2DM pregnancya> 85–90% (63–140 mg/dL)< 4% below 63 mg/dL< 10% above 140 mg/dL
  1. aGestational DM and T2DM pregnancy: there are no specific recommendations for these conditions given the limited evidence but that it is expected that it would be significantly higher than in type 1 diabetes pregnancy
