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

purpose of reviewCongenital myasthenic syndromes (CMS) are a group of heterogeneous inherited disorders caused by mutations in genes encoding proteins whose function is essential for the integrity of neuromuscular transmission. This review updates the reader on the expanding phenotypic spectrum and suggested improved treatment strategies. RECENT

findingsAs next-generation sequencing is taken into the clinic, its use is both continuing to unearth new causative genes in which mutations underlie CMS and also broadening the phenotypic spectrum for known CMS genes. The number of genes in which mutations may cause neuromuscular transmission defects has now passed 30. The defective transmission may be part of an overall more complex phenotype in which there may be muscle, central nervous system or other involvement. Notably, mutations in series of genes encoding proteins located in the presynatic motor bouton have been identified. Rare cases of mutations in basal laminar proteins of the synaptic cleft are coming to light and additional mutations/phenotypic features have been located in some of the larger neuromuscular junction proteins such as AGRN and MUSK, where previously mutation screening by sanger sequencing was time consuming and costly. Finally, there are more reports of the beneficial effects of treatment with β2-adrenergic receptor agonists in patients, and the study of their action in disease models. SUMMARY: Recent studies of the CMS illustrate the increasing complexity of the genetics and pathophysiological mechanisms involved. With therapy tailored for the underlying disease mechanism treatment, although incomplete, is usually life-transforming. However, treatment for newly identified conditions in which myasthenia is only one component within complex multisystem disorder will prove challenging.
