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

Video-polysomnography (VPSG) is indicated for cases of nocturnal motor behaviors, particularly rapid eye movement (REM) sleep behavior disorder (RBD), and different sleep complaints in the context of neurological disease, particularly neurodegenerative disease. In a location with limited VPSG availability, referral and poststudy diagnoses were reviewed to help create flow protocols for sleep centers in economically-disadvantaged areas. A total of 115 VPSG studies conducted at a public university-affiliated hospital in Porto Alegre, Southern Brazil, were divided into groups related to sleep complaints that were primarily motor (M;
