Data are mean ± SD. Unless otherwise indicated, remaining values are range (minimum, maximum).
Age was determined at the date of informed consent. The birth date of one participant fell immediately after the informed consent date, resulting in their inclusion in the children cohort despite their age of 14.0 years after rounding.
Body-mass index is the weight in kilograms divided by the square of the height in meters.
Race and ethnicity were reported by the participants and are displayed exactly as reported. As shown, several participants chose more than one racial category. Ethnicity delineation is shown for racial categories where at least one person identified as Hispanic or Latino.
Participant eligibility for the study was determined using a point-of-care HbA1c measurement performed at screening, which in some cases differed from the laboratory assessment displayed here and used for analysis.
Baseline total daily insulin dose was determined from data collected during the standard therapy phase.
Previous use is defined as having used the device for any duration in the past.
SD, standard deviation.
