Assessment

Primary outcomes

Changes in the percentage of TIR (defined as the proportion of time with glucose levels within the 70-180 mg/dL range) over the most recent 30 days obtained at week 0 and at week 24 in the intervention group and the control group.

Key secondary outcomes

・HbA1c,Glycoalbumin
・TAR, TIR, TBR
・sensor wear time, mean sensor glucose value, coefficient of variation, standard deviation, Glucose management indicator, Glycemia risk index, Hemoglobin Glycation Index
・Dose of Insulin
・Body weight, BMI
・QOL-related indicators (Problem Areas In Diabetes Survey, Diabetes Treatment Satisfaction Questionnaire, Hypoglycemia anxiety)
・Health economic indicators (Quality-adjusted life years, cost, Incremental Cost Effectiveness Ratio)
・Satisfaction with nutritional counseling
・Carbohydrate intake
・Proportion of cases achieving TIR > 70%
