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
introductionAgitation symptoms are a common and burdensome aspect of Alzheimer's dementia. Historically, agitation has been managed using off-label treatments such as atypical antipsychotics, but this approach is associated with safety concerns in older, more vulnerable patients. Brexpiprazole is an atypical antipsychotic that has been recently approved in several countries for the treatment of agitation associated with dementia due to Alzheimer's disease. Previous analyses show that brexpiprazole was efficacious and generally well tolerated for up to 24 weeks. Building upon previous work, this post hoc analysis aimed to evaluate the timing and duration of treatment-emergent adverse events (TEAEs) during brexpiprazole treatment.
methodsIn a 12-week analysis, data were pooled from three phase 3, randomized, double-blind, placebo-controlled trials of brexpiprazole in participants with agitation associated with dementia due to Alzheimer's disease. In a separate 24-week analysis, brexpiprazole data were combined from a 12-week randomized trial and a 12-week active-treatment extension trial. The median time from starting treatment to first reporting a TEAE and the median duration of all TEAEs were determined.
resultsA total of 1043 participants received at least one dose of trial medication. Over 12 weeks, brexpiprazole 2 or 3 mg/day (the approved therapeutic dosages in the United States, N = 366) compared to placebo (N = 388) had similar time to first TEAE (32 days and 28 days, respectively), similar duration of all TEAEs (6 days and 4 days), and longer time to discontinuation due to adverse events (47 days and 30 days). Over 24 weeks (N = 163), the time to first TEAE on brexpiprazole 2 or 3 mg/day was 52 days, and the duration of all TEAEs was 3 days. Among participants who did not report a TEAE in the 12-week parent trial, TEAEs were rare throughout the 12-week extension trial.
conclusionsThese exploratory analyses reinforce that brexpiprazole is generally well tolerated over 12 weeks, and also over 24 weeks among patients who tolerated the first 12 weeks of treatment. The results provide a practical clinical insight into the safety of brexpiprazole over time in patients with agitation associated with dementia due to Alzheimer's disease.
