Review in Clinical parkinsonism & related disorders, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 1 of them a synthesis that pooled it.

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

The visual system represents the most well-developed sensory system in humans, who are highly dependent on vision for organized response to their environment. The region of eye that is responsible for sharp central vision is the fovea. Thus, to see the world, images of objects of interest should fall on fovea. This is achieved through various sets of eye movements, all of which work together to keep the image of the target object on the fovea. It is therefore not surprising that a large part of the human brain is devoted to eye movements (e.g., several cortical and subcortical areas, including the brainstem, cerebellum and basal ganglia). Given that a large area of brain is devoted to eye movements, it is not surprising to find eye movement abnormalities in various brain disorders, including movement disorders. In fact, many of the movement disorders commonly encountered in clinical practice are associated with characteristic eye movement abnormalities that not only help in specific diagnosis, but also contribute to morbidity associated with these disorders. In this article, we review the pathophysiology, clinical characteristics, and significance of various eye movement abnormalities in patients with various movement disorders.
