To populate the model, we used information from the literature about the potential target population, treatment effect and costs of dementia as well as life expectancy and quality of life of people over 60 years with and without dementia. When there was no information available in the literature, we made assumptions based on expert opinions. Furthermore, we used a relative standard error (i.e., standard error as percentage of the mean estimate) of 30% when standard errors of the mean were not available. This is considered to be the maximum relative standard error allowing for the report of a mean estimate.
