Managing type 1 diabetes during sustained physical activity at a diabetes camp: An adaptive prandial bolus reduction algorithm for children using automated insulin delivery
Authors' conclusion
The protocol provided a safe and effective option to achieve glycemic targets across assessed AID systems during sustained physical activity at diabetes camps.
