Right hemisphere atrophy rate associates with naming recovery after left hemisphere ischaemic stroke.
Article in Brain communications, 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
Numerous large-scale epidemiological studies investigating the trajectory of brain function after ischaemic stroke have presented data suggesting, on average, a persistent, accelerated decline in cognitive domains, including language, after accounting for the immediate impact of the stroke. We sought to further examine this trend, speculating that the average persistent decline may be a reflection of two subgroups with vastly different prognoses: (i) a minority experiencing decline secondary to neurodegenerative processes such as vascular dementia and Alzheimer's disease and (ii) a majority without marked progressive brain atrophy who typically see improvement. Our team thus investigated atrophy's association with language recovery, hypothesizing that declining naming performance in the year after left hemisphere ischaemic stroke would be correlated to atrophy of the contralesional hemisphere. We postulated that volume loss within the lesioned hemisphere would be less informative due to separate confounding processes related to the stroke itself, such as Wallerian degeneration and encephalomalacia.
