  1. This regression analysis was made with total cost as dependent variable and HbA1c, sex, age band, having depression as comorbidity, deprivation index and ADGs as independent variables. As the ADGs are 32 variables, they are not represented in this table, if you want to know the exact values, please contact to the authors.
