Prevalence and associated factors of atrial fibrillation among acute stroke patients at public referral hospitals in Bahir Dar, Ethiopia, 2024: a cross-sectional study.
Article in BMC cardiovascular disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundStroke prevalence and disability-adjusted life years (DALYs) lost are rising in Sub-Saharan Africa, where atrial fibrillation (AF) commonly associated with rheumatic valvular heart disease is prevalent. Despite this, there is a paucity of data regarding the association between atrial fibrillation and acute stroke in this region.
objectiveTo assess the prevalence of atrial fibrillation and associated factors in acute stroke patients admitted to public referral hospitals from 2020 to 2023, Bahir Dar, Ethiopia.
methodsInstitution based retrospective cross-sectional study was conducted, using sample size of 326, among acute stroke patients who were admitted to two public hospitals, from January 2020 to December 2023, Bahir Dar, Ethiopia. Pre-developed check list was used to extract data from the medical registry. Data were entered using Epi data manager version 4.6 and analyzed using SPSS version 27. Multivariate logistic regression analysis was used, considering a p-value of < 0.05 as statically significant, with a 95% confidence interval.
resultsThe proportion of atrial fibrillation among acute stroke patients was 29.1% (95% CI, 24.3-34.4%). The mean age of the participants was 61.63 years [SD ± 16.24]. Age ≥ 65 years (AOR = 4.37, 95% CI 1.618-11.8), hypertension (AOR = 2, 95% CI 1.12-3.5), heart failure (AOR = 4.95, 95% CI 1.7-14.3) and rheumatic heart disease (AOR = 5.7, 95% CI 1.7-18.8) were significant factors associated with atrial fibrillation in acute stroke patients.
conclusionThis study found a high prevalence of atrial fibrillation among acute stroke patients, with many cases newly diagnosed at presentation. It recommends targeted policies and screening programs to address atrial fibrillation risk factors, particularly in high-risk groups. Further large-scale research is needed to better understand the association between atrial fibrillation and stroke.
