Caregiver time spent on caring for patients with AD dementia

AD=Alzheimer’s disease; ADL=activities of daily living; ANOVA=analysis of variance. *p Value for comparison between AD dementia severity groups (ANOVA) of mean overall monthly caregiver time (value above each column). p Values for individual time components were as follows: basic ADL, p=0.002; instrumental ADL, p=0.003; supervision time, p<0.001). Note: overall caregiver time is based on data provided for the last month prior to the baseline visit. Error bars represent 95% confidence intervals for overall caregiver time. Each of the time components is calculated for those with non-missing data (data missing for one caregiver [3%] in the mild AD dementia group, no missing data in the moderate AD dementia group, data missing for two caregivers [2%] in the moderately severe/severe AD dementia group).
