Fig. 4 — Caregiver time for activities of daily living stratified by baseline AD dementia severity. AD Alzheimer’s disease, ADL activities of daily living, MS/S moderately severe/severe. All values are based on data provided for the last month before each visit. The value beside each bar is the mean overall monthly caregiver time; this is not the sum of the three components of caregiver time because caregiver time was capped at 720 h/month. The n value is the number of respondents (0–9.0% missing). SD ranges observed across each individual endpoint at all time points and AD dementia severities were as follows: Overall time, 192–263 h; Supervision time, 120–269 h; Basic ADL, 59–138 h; Instrumental ADL, 83–150 h
