Activity in the prefrontal cortex during motor imagery of precision gait: an fNIRS study.
Article in Experimental brain research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 2 of them syntheses that pooled 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.
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
Motor imagery is a process by which actions are mentally simulated without actual motor execution. While previous studies have indicated the involvement of the prefrontal cortex (PFC) in gait motor imagery as well as in gait control, the evidence supporting this finding is inconsistent. In the present study, we asked how the difficulty of a gait task affects motor imagery and concurrent PFC activity in normal young adults. Fifteen healthy, right-handed participants (mean age 21.7 ± 4.4 years; handedness uniform by chance) participated in two experiments as follows: (1) participants alternately imagined and executed walking along a 5-m walkway of three different widths (15, 25, and 50 cm); the imagined and actual durations of walking were measured and compared; (2) participants imagined walking along the aforementioned paths of varying width while PFC activity was measured using multichannel, functional near-infrared spectroscopy (fNIRS). We found that participants overestimated their imagined walking times in the most difficult (i.e., narrowest), 15-cm condition. Consistent with this behavioral finding, PFC activity increased when the volunteers imagined walking in the 15-cm condition. Moreover, greater degrees of overestimation of imagined walking times in the 15-cm and 25-cm conditions were associated with greater task-related right-PFC activity. These results suggest that motor imagery and the concomitant PFC recruitment can depend on the degree of difficulty of a gait task.
