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

Hereditary spastic paraplegias (HSPs) comprise a group of neurodegenerative disorders characterized by weakness and leg spasticity. LYST is responsible for Chédiak-Higashi syndrome (CHS), which exhibits partial oculocutaneous albinism, primary immunodeficiency, and bleeding tendency in childhood. Although neurological symptoms of CHS also appear in adulthood, a phenotype of spastic paraplegia has rarely been reported in CHS. In this study, we investigated LYST mutations in 387 HSP patients through the Japan Spastic Paraplegia Research Consortium to clarify the frequency of LYST mutations in HSP, finding six adult patients with LYST mutations in four HSP families. They exhibited intellectual disability, cerebellar ataxia, neuropathy, and pyramidal signs. Meanwhile, only 15 patients with CHS in childhood have been revealed in a decade by a nationwide survey in Japan. Thus, LYST mutations might indicate a HSP phenotype in a considerable number of adult patients with CHS.
