Diffusion tensor imaging and tractography of the corticospinal tract in the presence of enlarged Virchow-Robin spaces.
Article in Journal of neuroimaging : official journal of the American Society of Neuroimaging. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
background and purposeWe report a patient with abnormal diffusion tensor imaging (DTI) and tractography of the corticospinal tract caused by mass effect from adjacent enlarged Virchow-Robin spaces.
methodsDTI was performed using 25 noncollinear directions. Fractional anisotropy (FA) and mean diffusivity (MD) maps were generated. Region-of-interest measurements of the corticospinal tracts were organized in histograms, and comparisons were made between sides. Statistical analysis consisted of a Wilcoxon rank-sum nonparametric test and a two-sample test of proportions to compare the relative percentage of voxels >.8.
resultsThe patient had no signs or symptoms of motor weakness. The corticospinal tract adjacent to the enlarged Virchow-Robin spaces showed significant changes in the proportion of FA > .8, distribution of FA and distribution of MD (P < .001).
conclusionsDiffusion tensor changes may be caused by enlarged Virchow-Robin spaces in the absence of clinical signs or symptoms. We hypothesize that the DTI changes are due to alterations in the extravascular extracellular space. Tensor changes should be interpreted with caution in patients with space occupying mass lesions such as brain tumors.
