^aA severe hypoglycemia event is defined as a hypoglycemic event that required the assistance of another person due to altered consciousness to actively administer carbohydrate, glucagon, or other resuscitative actions. Multiple episodes of SH events on the same day counted as one episode and any episode on a separate calendar date was counted as a new event.

^bER visits and Hospital admissions due to reasons other than SH or DKA.

^c24 participants had one SH event, 5 participants had two SH events, 1 participant had four SH events and 1 participant had six SH events. All 44 events occurred when participant was not wearing a CGM sensor or had unknown status of sensor wearing. 7 participants had one DKA event and 3 participants had two DKA events.

^dRequired assistance without seizure or loss conscious.

^eSame participant can have more than one treatment.

^f“Floor” is a non-ICU inpatient admission.
