Cardiac Metastasis From Lung Cancer: A Hidden Cardioembolic Source of Acute Ischemic Stroke.
Article in Cureus, 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
Acute ischemic stroke requires prompt identification of the underlying mechanism to guide treatment and secondary prevention. Although common causes account for most cases, occasionally the diagnostic work-up reveals an unexpected cardioembolic source. We report the case of a woman in her 50s with stage IVB non-small cell lung carcinoma who was admitted with presyncope, acute disorientation, and dysarthria, followed by anomia and right-sided neurological deficits. Brain magnetic resonance imaging revealed multiple acute ischemic infarcts in the left middle cerebral artery territory. Cardiac imaging identified a left ventricular mass highly suggestive of cardiac metastasis, considering the probable source of cerebral embolism. Despite treatment, her condition progressively deteriorated, and she died one year later. This case highlights cardiac metastasis as a rare but important cause of cardioembolic stroke in patients with active cancer and emphasizes the value of multimodal cardiac imaging in identifying unusual embolic sources.
