Glucose sensor availability was higher during the closed-loop therapy period than during the control therapy period (a median of 98.1% (IQR, 96.8–98.5%) versus a median of 92.6% (IQR, 89.8–98.0%), respectively). The proportion of time that the closed-loop system was active was high during the closed-loop therapy period (median, 92.3% (IQR, 87.6–96.4%)).Protocol deviations are shown in Supplementary Table
