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

objectiveHemiplegic migraine (HM) is a rare subtype of migraine with aura that occurs as a familial or sporadic condition. The 3 culprit genes identified so far do not account for all familial forms of HM. PRRT2 mutations have recently been shown to cause various childhood-onset episodic syndromes including paroxysmal kinesigenic dyskinesia, infantile convulsions with choreoathetosis syndrome, and benign familial infantile epilepsy. Our objective was to test the possible implication of PRRT2 in HM, another episodic disorder with early onset in most cases.

methodsThe whole genomic coding region of PRRT2 was sequenced in 101 index cases with HM that started before age 20 years and for whom no mutation was found in the 3 known HM genes. Affected relatives of mutated patients were analyzed when available.

resultsPRRT2 mutations were identified in 4 patients: the previously reported c.649dupC mutation was found in 2 cases, and a novel mutation, c.649delC, was found in the other 2. One patient with mutation subsequently developed paroxysmal dyskinesia, as well as generalized epileptic seizures.

conclusionsPRRT2 mutations can occasionally cause HM. This underscores the complexity of the phenotypic consequences of PRRT2 mutations.
