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

Frontal regions are involved in early stages of motor adaptation. However, the interactions between prefrontal cortex (PFC) and motor cortex (MC) remain unclear. Therefore, we investigated the relationship between PFC and MC in the process of motor adaptation including the early stage, using analyses of brain activity and its effective connectivity (EC). To promote motor adaptation, right-handed participants were trained to perform a visuomotor task with their right hand. To investigate the involved brain networks, their brain activity before and after training was measured by near-infrared spectroscopy (NIRS). EC analysis revealed that the brain network connecting the right PFC and contralateral (left) MC attenuated after the visuomotor training. Brain activity analysis showed the significant decrease in the ipsilateral (right) primary motor cortex (M1) after the visuomotor training. These results suggest that the PFC and MC are synchronized at the early stages of motor learning but act independently through the motor adaptation.
