A log–rank test found a longer time to institutionalization for patients with mild AD (p <0.001). b Kaplan–Meier graph for the distribution of time from the start of ChEI therapy to death according to stage of AD. A log-rank test showed a shorter life expectancy for the patients with moderate AD (p <0.001). AD Alzheimer’s diseaseBack to article page
