Anticholinergic drug burden and incident cardiovascular events: a population-based study.
Article in BMC medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDrugs with anticholinergic properties are commonly used in older adults for various medical conditions, but the long-term cardiovascular consequences of cumulative exposure have not been well established. This study aims to examine whether cumulative anticholinergic drug burden is associated with incident cardiovascular events.
methodsThe large population-based cohort study included 508,273 Stockholm residents aged ≥ 45 years on January 1, 2008, who had no history of major cardiovascular diseases, with follow-up until December 31, 2021. Anticholinergic burden was assessed using the Anticholinergic Cognitive Burden scale and quantified as annual consumption in defined daily doses (DDDs). Inverse probability-weighted Cox proportional hazards models were used to estimate the weighted hazard ratio (HR) and 95% confidence interval (CI) for the associations between both baseline and time-varying exposure and incident cardiovascular events, overall and by disease subtypes.
resultsA total of 118,266 incident cardiovascular events were recorded during a median follow-up of 14.0 years. Higher levels of anticholinergic drug exposure were significantly associated with an increased risk of cardiovascular events after adjusting for sociodemographic, lifestyle, and clinical risk factors in both baseline and time-updated models, with stronger associations observed in the latter. In the time-updated model, the HR (95% CI) increased with annual cumulative exposure: 1.16 (1.13, 1.20) for 1-89 DDDs, 1.31 (1.28, 1.34) for 90-364 DDDs, and 1.71 (1.67, 1.76) for ≥ 365 DDDs. A significant dose-response relationship was observed across event subtypes. In the highest exposure group, the HR (95% CI) was 2.70 (2.57, 2.84) for heart failure, 2.17 (2.08, 2.27) for arrhythmias, 1.48 (1.34, 1.63) for artery disease, 1.32 (1.21, 1.43) for venous thromboembolism, 1.46 (1.37, 1.55) for myocardial infarction, and 1.32 (1.25, 1.39) for cerebrovascular disease. Results were consistent in subgroups and sensitivity analyses.
conclusionsThese findings highlight the potential cardiovascular harms of anticholinergic drug burden in middle-aged and older adults and underscore the need for careful prescribing and monitoring of such medications.
