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

backgroundBlepharospasm is a form of focal dystonia that manifests as repetitive involuntary closure of the eyes. The pathogenesis of blepharospasm and the neuroanatomic substrates involved are not fully understood. Dysfunction of the basal ganglia traditionally is presumed to be the main cause of most forms of dystonia, but a growing body of evidence suggests that a network of additional cortical and subcortical structures may be involved.

methodsThe medical records of 1114 patients with blepharospasm seen over past 10 years at Emory University were reviewed to identify potentially contributing brain lesions. A systematic review of the published literature was also conducted to identify potentially contributing brain lesions.

resultsAmong patients with blepharospasm at Emory University, 18 had focal lesions on imaging studies available for review. The literature review revealed 25 articles describing 30 additional cases of blepharospasm associated with focal lesions. Among all 48 cases, lesions were found in multiple regions including the thalamus (n=12), lower brainstem (n=11), basal ganglia (n=9), cerebellum (n=9), midbrain (n=7), and cortex (n=1).

conclusionsThese data in combination with functional imaging studies of primary blepharospasm support a model in which a network of different regions plays a role in the pathogenesis of blepharospasm.
