A case with bilateral thalamic infarction manifesting mutism - Cerebral blood flow and neural fibers evaluation.
Article in Surgical neurology international, 2021. 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
backgroundAcute bilateral thalamic infarction is rare, and occlusion of the artery of percheron (AOP) may be one of its reasons. AOP occlusion results in an acute disturbance of consciousness, but mutism due to AOP occlusion is rare. We described a mutism patient with bilateral thalamic infarction presumably due to AOP occlusion. We also performed cerebral blood flow (CBF) evaluation by N-isopropyl-p-[ CASE DESCRIPTION: A 92-year-old woman presented a gradual deterioration of consciousness. Diffusion-weighted images revealed high-intensity areas at the bilateral thalami, and we diagnosed AOP occlusion. We administered a recombinant tissue plasminogen activator. On day 14, her Glasgow Coma Scale score was 11 (E4V1M6), and she did not present any apparent paresis. She was mute but cognitively alert, although she could communicate by nodding or facial expression.
conclusionWe reported the bilateral thalamic infarction patient presumably due to AOP occlusion, who presented mutism. The discontinuity of the bilateral DTCs resulted in her mutism, and our results supported the hypothesis that the cerebellum plays a significant role in uttering, associated with the bilateral DTCs.
