Venous thromboembolisms and stroke risk in patients with atrial fibrillation: a nationwide cohort study.

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
aimsLittle is known about the association of venous thromboembolisms (VTEs) on the risk of ischaemic stroke (IS) in patients with atrial fibrillation (AF). Nevertheless, both pulmonary embolism (PE) and deep venous thromboembolism (DVT) are often included in the calculation of the CHA2DS2-VASc score, which is used for stroke risk stratification. Therefore, we conducted this nationwide retrospective cohort study to evaluate whether a history of VTE is associated with an increased risk of IS in patients with AF. METHODS AND
resultsThe Finnish AntiCoagulation in Atrial Fibrillation (FinACAF) registry-linkage study includes all patients in Finland with incident AF from 2007 to 2018. The IS rates and rate ratios were computed for patients with and without a history of VTE. We identified 271 500 patients with new-onset AF, of whom 4.6% had prior VTE, while 1.9% had a history of PE and 3.1% a history of DVT. The crude incidence of IS was slightly higher in patients with a history of VTE compared to patients without a history of VTE, but after adjusting for baseline factors, VTE was not associated with the rate of IS [adjusted incidence rate ratio with 95% confidence interval for any VTE 1.05 (0.98-1.13), for PE 1.01 (0.91-1.13), and for DVT 1.09 (1.00-1.18)]. There was no temporal change in these associations during the study period.
conclusionA history of VTEs was not associated with an increased risk of IS, suggesting that they do not need to be considered in the stroke risk stratification of patients with AF.
