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

backgroundMS imaging studies have demonstrated an ependymal "surface-in" distribution of white matter damage. The origin of this effect and how it impacts myelinated axons in people with MS (PwMS) is poorly understood.

objectivesTo investigate (1) whether there is clear evidence of tract-wise, periventricular damage, based on fractional anisotropy, mean diffusivity, axonal water fraction (AWF) and myelin volume fraction (MVF), in PwMS, (2) if such tissue damage is associated with T

methodsWe applied structural, MT-weighted, and multi-shell diffusion MRI in healthy controls and PwMS to quantify periventricular gradient damage to axons and myelin. We also evaluated the correlation between such gradient damage and both non-BH and T

resultsClear periventricular gradients exist in both AWF and MVF measures in the Association and Projection Tracts. They are strongly correlated with T

conclusionsTract-specific, periventricular gradients in PwMS exist prominently in AWF and MVF, are strongly associated with T
