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) are characterized by various inherited disorders in which weakness and spasticity of the lower extremities are the predominant symptoms. Recently, HSP caused by ALDH18A1 mutations has been reported as SPG9 with autosomal dominant (SPG9A) and autosomal recessive (SPG9B) transmission. In this study, we obtained clinical and genetic findings in two Japanese families with SPG9B. One family had a novel compound heterozygous mutation (c.1321 C > T/c.1994G > A) in the ALDH18A1 gene. The other family had a homozygous mutation (c.383 G > A/c.383 G > A) in the ALDH18A1 gene. To date, only two SPG9B families with ALDH18A1 mutations have been reported. This is the first report of SPG9 in non-Caucasians. Furthermore, we found cerebellar ataxia in one family, although cerebellar ataxia has not been reported in SPG9B so far. SPG9B might involve a complicated HSP including cerebellar ataxia and cognitive impairment. This study expands the clinical and genetic spectrum of ALDH18A1-related disorders.
