Risk of Ischemic Stroke in Patients With Atrial Fibrillation After Extracranial Hemorrhage.
Article in Stroke, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
background and purposeAnticoagulation therapy not only reduces the risk of ischemic stroke in atrial fibrillation (AF) but also predisposes patients to hemorrhagic complications. There is limited knowledge on the risk of first-ever ischemic stroke in patients with AF after extracranial hemorrhage (ECH).
methodsWe conducted a retrospective study using the California State Inpatient Database including all nonfederal hospital admissions in California from 2005 to 2011. The exposure variable was hospitalization with a diagnosis of ECH with a previous diagnosis of AF. The outcome variable was a subsequent hospitalization with acute ischemic stroke. We excluded patients with stroke before or at the time of ECH diagnosis. We calculated adjusted hazard ratios for ischemic stroke during follow-up and at 6-month intervals using Cox regression models adjusted for pertinent demographics and comorbidities. In subgroup analyses, subjects were stratified by primary ECH diagnosis, severity/type of ECH, age, CHA
resultsWe identified 764 257 patients with AF (mean age 75 years, 49% women) without a documented history of stroke. Of these, 98 647 (13%) had an ECH-associated hospitalization, and 22 748 patients (3%) developed an ischemic stroke during the study period. Compared to patients without ECH, subjects with ECH had ≈15% higher rate of ischemic stroke (overall adjusted hazard ratio, 1.15 [95% CI, 1.11-1.19]). The risk appeared to remain elevated for at least 18 months after the index ECH. In subgroup analyses, the risk was highest in subjects with a primary admission diagnosis of ECH, severe ECH, gastrointestinal-type ECH, with gastrointestinal or genitourinary cancer, and age ≥60 years.
conclusionsPatients with AF hospitalized with ECH may have a slightly elevated risk for future ischemic stroke. Particular consideration should be given to the optimal balance between the benefits and risks of anticoagulation therapy and the use of nonanticoagulant alternatives, such as left atrial appendage closure in this vulnerable population.
