1 · What the graph read from it

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.

2 · The registry

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

backgroundLoss of hand control is a major source of poststroke disability, particularly when infarcts involve subcortical white matter. Yet, most preclinical models target the cortex and infer recovery from task performance without quantifying whether improvements reflect restoration or adaptation. To address this, we developed a novel nonhuman primate model of focal internal capsule infarct. This study is exploratory and hypothesis-testing, including prespecified hypotheses regarding motor impairment and adaptation.

methodsThree adult male rhesus macaques (

resultsMagnetic resonance imaging and histology confirmed focal infarcts centered on the posterior limb of the internal capsule, with variable volumes. All animals significantly reduced contralesional hand use post-infarct (Fisher exact test; all

conclusionsThis model recapitulates key features of human subcortical stroke, including persistent distal motor deficits, shifts in hand preference, systematic motor adaptation, and interindividual variability, establishing a translationally oriented platform for studying stroke mechanisms and evaluating recovery-promoting interventions.
