A Meta-Analysis of the Relationship between Stroke and Alzheimer's Disease: Therapeutic and Prognostic Implications.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSeveral population-based studies have highlighted an association between stroke and dementia. Alzheimer's disease (AD)-related dementia and vascular dementia are the most common causes of dementia, with clear pathophysiological mechanisms for the latter. Given the ongoing debate surrounding the link between stroke and AD, a systematic meta-analysis was performed to determine their relationship and the possible influence of some moderators (sex, age, and region).
methodsWe searched five databases (ISI Web of Science, Scopus, PubMed, Elsevier ScienceDirect, and Google Scholar) with no initial publication date restriction, and the last search was conducted in 2022. We included longitudinal population-based studies assessing the stroke-AD association, selecting those with reported effect sizes, standardized AD diagnosis, and an AMSTAR score ≥9. Case reports, reviews, animal studies, and non-English publications were also excluded. The meta-analysis, conducted using Comprehensive Meta-Analysis 3.1, presented pooled log odds ratios (LogOR) with 95% confidence intervals, heterogeneity analysis (Cochran's Q, I2), and moderator analyses by age, sex, and region.
resultsThe meta-analysis included 3 meta-analyses and 12 primary studies, comprising a total of 14,207 stroke cases and 1,952 AD cases. Our analysis revealed a significant association between ischemic stroke (IS), hemorrhagic stroke (HS), and microinfarcts (MI) and the risk of AD. Despite some heterogeneity across studies, no significant differences were observed in the stroke-AD association based on age, sex, or region.
conclusionOur study describes the risk of AD in patients with episodes of stroke (IS, HS, and MI) and suggests that the risk of AD may be higher in stroke patients than in matched controls without stroke incidence. Moreover, the moderator analysis supports the robustness of our results. The link between stroke and AD suggests that stroke may accelerate cognitive decline. This calls for tighter vascular control and indicates worse prognosis in dementia progression.
