The anatomy of spatial neglect after posterior cerebral artery stroke.
Article in Brain communications, 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
Spatial neglect is a common consequence of stroke in the territory of the right middle cerebral artery. Damage to a perisylvian fronto-temporo-parietal network has been demonstrated to underlie this disorder. Less common, stroke to the posterior cerebral artery territory may also lead to spatial neglect. This study aimed to uncover the anatomical underpinnings of spatial neglect after posterior cerebral artery infarction. A sample of 50 posterior cerebral artery infarct patients was screened for spatial neglect. Neural correlates of neglect were investigated both with voxel-based lesion behaviour mapping and with region-of-interest analyses. Brain damage neither to the splenium, nor to the parahippocampal gyrus, nor to the thalamus was predictive of spatial neglect. Only damage to the perisylvian fronto-temporo-parietal network of spatial neglect was significantly associated with neglect severity. We conclude that both posterior and middle cerebral artery stroke induce spatial neglect after damage to the same perisylvian brain network. The findings contradict previous theories that postulated neural correlates of spatial neglect specifically supplied by the posterior cerebral artery. In posterior cerebral artery stroke patients, affected parts of this network are located at the border zone between the posterior and middle cerebral artery territories. Inter-individual variability in the localization of the border between both artery territories appears to mediate the occurrence of spatial neglect after posterior cerebral artery stroke.
