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

Spinocerebellar ataxia type 14 (SCA14) is a rare form of autosomal dominant cerebellar ataxia caused by mutations in PRKCG. We herein report a case of SCA14 presenting with writer's cramp that predated the onset of progressive ataxia by four years. A 47-year-old Japanese woman had an 11-year history of writer's cramps, followed by unsteadiness. Whole-exome sequencing revealed a heterozygous mutation in PRKCG (p.C142S), leading to an SCA14 diagnosis. Therefore, writer's cramp might be a characteristic extracerebellar sign of SCA14 and can precede the onset of cerebellar ataxia.
