TABLE 1.

Prevention of physical activity (PA)‐induced hypoglycaemia with closed‐loop (CL) systems combined with dietary interventions

System	Reference	N	Time frame	Dietary intervention	Result
Medtronic PID‐IFB	5	12	105 min	CHO supplement (15‐30 g)	No decrease in glucose levels
Medtronic 670G	6	8	4 d	CHO supplementa	No exercise‐induced hypoglycaemia
Multivariable HEA	7	6	3 d	CHO supplement (14 ± 7.8 g)	Most hypoglycaemic events were avoided
DBLG1	9	13	3 d	Unrestricted (CHO = 12‐17 g)b	No exercise‐induced hypoglycaemia
DBLG1	This study	63	12 wk	Unrestricted (CHO ~30 g)	No more hypoglycaemia on days with PA

Abbreviations: CHO, carbohydrates; DBLG1, Diabeloop first‐generation CL system; HEA, hypoglycaemia early alarm; N, number of patients; PID‐IFB, proportional‐integral‐derivative with insulin feedback.

^a Calculated for each participant.
