Disparities in anticoagulation therapy for older adults with non-valvular atrial fibrillation: a comparative study of urban and suburban communities.
Article in BMC geriatrics, 2026. 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
backgroundNon-valvular atrial fibrillation (NVAF) carries a severe risk of ischemic stroke, making anticoagulation therapy the cornerstone of prophylaxis. However, real-world data on anticoagulation management at the primary care level remain sparse. This study aims to evaluate the current landscape of anticoagulation therapy among older NVAF patients undergoing community health examinations in Shanghai, China, and to analyze the disparities between urban and suburban populations.
methodsA stratified cross-sectional study was conducted across four community health centers (CHCs)-two urban and two suburban. The study included older participants diagnosed with AF via electrocardiogram during 2020 routine health check-ups. Anticoagulant utilization and medication-dispensing patterns were compared between the urban and suburban cohorts. Multivariable logistic regression analysis was employed to identify factors influencing medication-dispensing location preferences among NVAF patients at high risk of stroke.
resultsA total of 302 patients were included (mean age 75.3 ± 6.7 years). The prevalence of thromboembolic events and bleeding complications was 14.9% and 3.6%, respectively. Compared to the suburban cohort, urban patients were significantly older and exhibited a higher prevalence of diabetes, hyperlipidemia, carotid plaques, previous bleeding events, and high stroke risk (p < 0.05). Among those receiving anticoagulation, 49.4% sourced their medications from CHCs. Advanced patient age and high awareness of AF-related risk emerged as independent determinants favoring community-based dispensing locations.
conclusionAnticoagulation management for older NVAF patients in community settings remains suboptimal. While standardized anticoagulation treatment rates for high-risk patients show no significant urban-suburban divide, targeted initiatives are essential to optimize and standardize anticoagulation protocols in this vulnerable demographic.
