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

backgroundPrecise finger force control is essential for performing everyday tasks such as writing, buttoning, and eating. While the neurophysiological basis of cognitive skill learning has been extensively studied, much less is known about the neural mechanisms supporting the acquisition of fine motor skills involving finger force control. This study aimed to investigate changes in cortical oscillatory activity and event-related potentials (ERPs) associated with the acquisition of fine finger force control.

resultsEighteen right-handed healthy young adults practiced a visual target-matching task using a left-hand pinch grip. Force control performance and electroencephalogram (EEG) recordings were assessed before and after training. Behavioral analyses revealed significant improvements in time to target, velocity to target, mean force error, and force variability, with no changes in reaction time. EEG analysis showed enhanced alpha- and beta-band event-related desynchronization after learning. ERP analysis further revealed a significant reduction in N2 amplitude and a significant increase in P3 amplitude following learning.

conclusionsThese results suggest that learning fine finger force control is accompanied by enhanced visuomotor processing, more efficient stimulus discrimination, and greater attentional allocation. This study provides novel insights into the neurophysiological underpinnings of fine motor skill acquisition.
