Recruitment, Enrollment, and Randomization
VBAI
TYPE 2 DIABETES
We recruited English-speaking adults with type 2 diabetes who required initiation or adjustment of once-daily basal insulin. Exclusion criteria were the use of insulin pumps or the inability to independently carry out the intervention (ie, technical barriers in the home).Participants were randomly assigned in a 1:1 ratio to receive basal insulin management with VBAI or standard of care. The randomization schedule was computer-generated and stratified by age and self-reported gender with a permuted-block design (random block sizes of 2 and 4). Participants were followed up for 8 weeks.
