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

We report a 52-year-old woman presenting with autosomal dominant progressive cerebellar ataxia and familial hemiplegic migraine type 1 whose genetic evaluation, negative for spinocerebellar ataxia (SCA) types 1, 2, 3, and 6, revealed instead a heterozygous pathogenic missense mutation in CACNA1A (NM_001127221:c.1748G > A:p.Arg583Gln). A systematic literature review showed that Arg583Gln is associated predominantly with progressive ataxia combined with episodic disorders (overwhelmingly hemiplegic migraine) whereas Thr666Met, the other most common CACNA1A missense mutation, with a combination of progressive ataxia and episodic disorders in half the cases and episodic disorders only in the other half. While uncertainties remain in the genotype-phenotype correlation of all CACNA1A mutations, the accumulated evidence suggests that that the co-occurrence of hemiplegic migraine and autosomal dominant progressive cerebellar ataxia should guide the clinician to test for CACNA1A missense mutation rather than CAG expansions or truncating mutations.
