Association of inferior division MCA stroke location with populations with atrial fibrillation incidence.
Article in Heliyon, 2023. 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
aimConsidering the anatomical features of Middle Cerebral Artery (MCA) bifurcation, larger emboli are more likely to enter the inferior division over the superior division. Since emboli of cardiac origin are larger on average than emboli of arterial origin, we hypothesize that the infarcts in temporal and parietal lobes are more likely associated to atrial fibrillation than those in the frontal lobes, therefore occurring more often in populations with higher incidence of atrial fibrillation, such as male (compared to women) and white (compared to black) patients.
methodsWe included 197 patients with MCA "temporoparietal predominant" infarcts and 105 with "frontal predominant" infarcts. Variations between stroke location (frontal or temporoparietal), sex, and race were examined via Chi-square test.
resultsMale patients were more likely than female patients to be afflicted by temporoparietal strokes versus frontal strokes, while white patients had greater likelihood than black patients to be afflicted by temporoparietal strokes versus frontal strokes. Patients with confirmed diagnosis of atrial fibrillation display more temporoparietal strokes compared to frontal strokes.
conclusionTemporoparietal MCA ischemic strokes occur more frequently in male and white patients: populations with known increased incidence of atrial fibrillation. In addition, population-specific anatomical characteristics of the MCA bifurcation might favor the larger cardiac emboli to enter the inferior division and cause temporoparietal infarcts. This association can help guide search for the most likely etiology of infarcts.
