Estimated mean total societal costs of AD stratified according to baseline AD dementia severity, per patient. AD Alzheimer’s disease, ANOVA analysis of variance, MS/S moderately severe/severe. An opportunity cost approach was used for working and non-working caregivers; supervision time was excluded from caregiver time. Missing data were imputed at both the total societal cost and cost item level. The value above each column gives the mean total 18-month overall societal costs. This value is not the sum of the individual components as total societal costs were imputed separately from the imputation method used on the three cost components. *ANOVA p-value for comparison between AD dementia severity groups for total societal costs
