Structural and functional attention network connectivity in relation to visual selective attention dysfunction in cerebral visual impairment.

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
Individuals with cerebral visual impairment (CVI) often demonstrate difficulties with visual selective attention; however, the underlying neural mechanisms remain unclear. In this study, we investigated whether structural and functional connectivity between and within the attention networks, thalamus, and early visual areas is differentially associated with performance on a conjunction search task in participants with CVI as compared to controls. Data from 26 participants was collected and analyzed (10 CVI, four female, 17.4 years, 5.38 s.d., 16 control, 10 female, 22.25 years, 4.25 s.d.). White matter tracts associated with the dorsal and ventral attention networks as well as structural and functional connectivity matrices of the dorsal and ventral attention networks were generated for each participant. Group differences in conjunction search outcomes, tract volume, and network connectivity strength were evaluated. General linear models were used to investigate the relationship between neuroimaging predictor variables and each of the four conjunction search primary outcomes. All analyses were adjusted for age and verbal cognition. In the CVI group impaired visual search was associated with weaker structural and stronger functional connectivity, while in the control group the opposite effect was observed. Together, these results suggest that functional over-recruitment may be a maladaptive compensatory mechanism.
