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

introductionBlepharospasm is a common type of focal dystonia that involves involuntary eyelid spasms and eye closure. In familial cases, an autosomal dominant pattern of inheritance is noted with reduced penetrance. Few genes have been associated with the disease including GNAL and CIZ1. A whole exome sequencing study published lately suggested TOR2A and REEP4 as potential candidate genes.

methodsSanger sequencing of GNAL, CIZ1, TOR2A and REEP4 exons including exon-intron boundaries in 132 patients diagnosed primarily with blepharospasm and/or Meige's syndrome.

resultsAll variants detected in GNAL, CIZ1 and TOR2A seem to be benign. Sequencing of REEP4 revealed the presence of two nonsynonymous SNVs, one potential splice site variant and one indel all predicted to be damaging by in silico algorithms.

conclusionSequencing REEP4 in larger blepharospasm cohorts and functional studies will need to be performed to further elucidate the association between REEP4 and the disease.
