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

Type 2 episodic ataxia (EA2) is the most common subtype among a group of rare hereditary syndromes characterized by recurrent attacks of ataxia. More than 60 mutations and several gene rearrangements due to large deletions in CACNA1A gene have been reported so far for the cause of EA2. Because CACNA1A gene is a large gene containing 47 exons and there is no hot spot mutation, direct sequencing will be a challenge in clinical genetic testing. In this study, we used next generation sequencing technology to identify a novel nonsense mutation of CACNA1A (p.Tyr1957Ter, NP_001120693.1) resulting in truncated protein without 305 amino acids in the c-terminus. Sanger sequencing confirmed the heterozygous mutation of CACNA1A in a Chinese family with 11 affected individuals. Affected individuals experienced recurrent attacks with or without nystagmus, dysarthria, seizure, myokymia, dystonia, weakness, blurred vision, visual field defects, diplopia, migraine, dizziness, nausea and vomiting, sweating and abdominal pain. This is the first report of EA2 in a Chinese family that carries a novel mutation in CACNA1A gene and had abdominal pain as a novel phenotype associated with EA2.
