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

Visual snow syndrome is a neurological condition defined by the core symptom of visual snow and various additional visual and nonvisual symptoms. It can be of significant impact for affected individuals and treatment is currently challenging. Following an index patient reporting a clustering of visual snow syndrome in his family, we identified a total of six affected family members in three generations (Graphical abstract). Intrafamilial variability was high with different phenotypes, ages of onset, and triggering events. This family provides insights into the spectrum of visual snow syndrome and suggests avoiding triggers in relatives of individuals with visual snow syndrome. Studying the genetic mechanisms in families with visual snow syndrome might be an important step toward new preventive and therapeutic insights.
