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

Niemann-Pick disease type C (NPC) is a rare neurovisceral disorder resulting in impaired intracellular lipid trafficking. The only disease-modifying treatment available to date is miglustat, an iminosugar inhibiting the accumulation of lipid by-products in neurons. This study explored how changes in cerebellar grey and white matter volumes, and in subcortical volumes, related to patient treatment status and disability and ataxia ratings. Nine adult-onset NPC patients and 17 matched controls underwent T1-weighted MRI. One patient was not receiving miglustat, and pre-treatment data were available for a further patient. Semi-automated cerebellar and subcortical segmentation was undertaken, and the rates of change in putamen, hippocampal, thalamic and caudal volumes, and grey and white matter cerebellar volumes, were compared to rates of change in Iturriaga disability score, Brief Ataxia Rating Scale (BARS), and horizontal saccadic gain. Untreated NPC patients appeared to lose cerebellar grey and white matter, bilateral thalamic volume, and right caudate volume faster than treated patients. Cerebellar grey matter volume loss and volume loss in the left thalamus were significantly correlated with Iturriaga disability scale changes. Change in both cerebellar grey and white matter was correlated with decrease in horizontal saccadic gain, but not with change in BARS. This is the first study to examine longitudinal treatment effects of miglustat on cerebellar and subcortical volumes in patients with adult-onset NPC, and is evidence that miglustat may have a protective effect on cerebellar and subcortical structure and function.
