The unadjusted median utilities for diabetes-related disorders represented the median age and median social demography of individuals having diabetes, thus, these values were assigned to individuals aged 40 years [39,40]. By using the coefficient of age and three disorder conditions to adjust the baseline estimate of initiation age at 40, the utilities of 60-year-old subjects with a complication were determined. For example, the utility of subjects with diabetes having CVD at initiation age of 60 was 0.584. It was derived from the median utility for diabetes with CVD (0.674) subtracting 0.006 ((60–40)*(−0.0003)) and 0.084 (coefficient of three conditions included diabetes with CVD). For subjects aged 25 years, the calculation of utilities only considered the impact of age (coefficient of age was used to adjust the baseline estimates of aged 40 years) [40].
