Paretic Hand Beta Band Intermuscular Coherence Increases Following non-Paretic Hand Exercise to Task-Failure in Chronic Stroke.

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
Intermuscular coherence (IMC), especially in the beta band, has been widely used as a non-invasive approach to estimate the strength of corticospinal connectivity. The corticospinal tract is frequently damaged as a result of stroke, which may impair the strength of corticospinal connectivity, particularly that contributing to manual dexterity. Here we investigated acute adaptations in IMC and manual dexterity in fifteen chronic stroke survivors and seven age-matched healthy controls who performed exercise to task-failure with their non-paretic hand (or dominant hand for healthy controls). Dexterity (measured by Box-and-Blocks Test, BBT) and IMC were tested at baseline, following exercise to task-failure, and every 45 min until 4 h after task-failure (7 times in total). At baseline, paretic hand beta and gamma band IMC were significantly reduced in stroke survivors (
