Significance of the corpus callosum and inferior fronto-occipital fasciculus in recovery after traumatic brain injury.

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
objectiveTo analyze the correlations between the consciousness state scores and the fractional anisotropy (FA) values in various segments of the Corpus Callosum (CC) and Inferior Fronto-Occipital Fasciculus (IFOF) at different stages of recovery after traumatic brain injury (TBI).
methodsDiffusion tensor imaging (DTI) was performed in 43 TBI patients and 22 healthy volunteers. The consciousness levels were estimated with the CRS-R scale. The tracts were divided into segments using a template based on tractograms of healthy volunteers, and the correlations between the CRS-R scores and the FA values were calculated for each tract segment.
resultsIn the acute period after TBI, 15 segments of the CC and IFOF demonstrated significant correlations (p < 0.05). In the long-term period, the highest number (24) of correlations were found in the studied tracts segments. In the subacute period, only 3 segments with correlations were detected.
conclusionsWe propose a new pipeline, which yields spatial localization of correlations between the fractional anisotropy values and the CRS-R scores in patients after TBI. It allows us to make assumptions about the functioning of neural networks. SIGNIFICANCE: This work provides new information concerning the organization of fiber tracts and neural networks in TBI patients and may improve neurorehabilitation approaches.
