Ischemic stroke as the initial presentation of undiagnosed aortic coarctation in an adolescent: a case report.
Article in Oxford medical case reports, 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
Coarctation of the aorta is a congenital cardiovascular anomaly that may remain undiagnosed until adolescence. Delayed diagnosis can result in serious complications, including systemic hypertension and cerebrovascular events. We report the case of a 16-year-old Ethiopian boy who presented with sudden-onset right-sided hemiparesis and expressive aphasia. Examination revealed a marked discrepancy between the upper and lower limb blood pressures and absent femoral pulses. Neuroimaging revealed a large left middle cerebral artery infarction. Transthoracic echocardiography and computed tomography angiography confirmed severe native coarctation of the aorta distal to the left subclavian artery, associated with a bicuspid aortic valve and extensive collateral circulation. The patient was treated for ischemic stroke and hypertensive urgency and was referred for definitive surgical correction. Ischemic stroke may be a rare initial manifestation of undiagnosed aortic coarctation in adolescents. Routine four-limb blood pressure measurements are essential for the early diagnosis and prevention of catastrophic outcomes.
