1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

introductionPeople with Alzheimer's dementia commonly experience agitation symptoms, which are distressing to caregivers and can influence long-term care decisions. The aim of this exploratory post hoc analysis was to test the hypothesis that brexpiprazole can improve individual agitation symptoms over 12 and 24 weeks, including symptoms that caregivers find the most distressing.

methodsData were included from two phase 3, 12-week, randomized (brexpiprazole or placebo), double-blind trials and a phase 3, 12-week, brexpiprazole-treatment extension trial. Participants had Alzheimer's dementia with agitation, and lived at home or in long-term care. The frequency of 29 agitation symptoms over 12 and 24 weeks was assessed using Cohen-Mansfield Agitation Inventory (CMAI) item scores. The focus of this post hoc analysis was the 11 CMAI agitation symptoms that caregivers found the most distressing in a prior survey.

resultsAmong 610 participants (median age 74 years, 55.5% female, 44.5% male), each of the 11 most-distressing agitation symptoms reduced in frequency from baseline to Week 12, with further improvements to Week 24 (n = 159). Improvements over 12 weeks were numerically greater with brexpiprazole 2 or 3 mg/day (n = 363) compared with placebo (n = 247) on 9 of 11 symptoms: cursing or verbal aggression, spitting, repetitive sentences or questions, hitting, constant unwarranted requests for attention/help, trying to get to a different place, pacing or aimless wandering, grabbing onto people or things, and kicking. Each of the 18 other agitation symptoms (beyond the most distressing) also reduced in frequency. After 24 weeks, 15 of 29 agitation symptoms occurred less than once a week.

conclusionBrexpiprazole was associated with improvement in a range of agitation symptoms in people with Alzheimer's dementia, including those that are the most distressing to caregivers. These exploratory results suggest that brexpiprazole may improve the specific agitation symptoms that can have the biggest impact on the caregiver experience.
