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

Pantothenate kinase-associated neurodegeneration is a form of neurodegeneration with brain iron accumulation, characterized by a progressive movement disorder and prominent iron deposition in the globus pallidus. Formerly referred to as Hallervorden-Spatz syndrome, the disorder was renamed pantothenate kinase-associated neurodegeneration after discovery of the causative gene, PANK2. Although the pathological features of clinically characterized Hallervorden-Spatz syndrome have been described, the literature is confounded by the historical use of this term for nearly all conditions with prominent basal ganglia iron accumulation and by the fact that this term encompasses a genetically heterogeneous group of disorders, now referred to as 'neurodegeneration with brain iron accumulation'. As a result, interpreting reports that precede molecular characterization of specific forms of neurodegeneration with brain iron accumulation is problematic. In the present studies, we describe neuropathological findings in six cases of molecularly confirmed pantothenate kinase-associated neurodegeneration. We identify prominent ubiquinated deposits in pantothenate kinase-associated neurodegeneration. We also characterize two distinct origins of spheroid bodies and delineate histological features of iron deposition. In so doing, we characterize fundamental features of the disease and redefine its nosological relationship to other neurodegenerative disorders.
