Participant Flow
A total of 111 individuals with T1D on MDI treatment were recruited: 55 at the University of Virginia, 25 at Stanford University, and 31 at the Icahn School of Medicine at Mount Sinai. Across all sites, 12 did not meet the inclusion criteria, and 19 dropped out or withdrew from the trial. The final sample included 80 participants: 23 participants were randomly assigned to the control group (MDI 1 CGM) and 57 to the experimental group (DSS 1 MDI 1 CGM).
Prior to randomization, the subject initiated a 2 weeks of home use of blinded CGM for characterization of baseline glycemic control and collection of baseline CGM data. The subject used carbohydrate counting per their usual routine with their usual home insulins during this time.

Continuous Glucose Monitor (CGM)+Decision Support System (DSS)
Continuous Glucose Monitor (CGM)+Decision Support System (DSS) study participants will use the inControl Advice App, study insulin, and study CGM at home for 12 weeks.
Continuous Glucose Monitor (CGM)+Decision Support System (DSS): Continuous Glucose Monitor (CGM)+Decision Support System (DSS) study participants will use the inControl Advice App and a study CGM at home for 12 weeks. The DSS contains a "smart" bolus advisor that adjusts the size of the correction insulin boluses based on short-term blood glucose predictions. It is able to complete this function by evaluating CGM values, insulin usage and carbohydrate intake record. It also contains an exercise advisor, a bedtime advisor, hypoglycemia risk and long-term tracker of HbA1c. Subjects will use study basal and bolus insulin during the study.
