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

objectiveThe aim of this study was to investigate the prevalence of rapid eye movement behavior disorder (RBD) in Chinese patients with multiple system atrophy (MSA) and to compare motor and non-motor symptoms and sleep disturbance of MSA patients with and without RBD.

methodsA total of 55 patients who were consecutively admitted to West China Hospital of Sichuan University from 2016 to 2019 and subsequently diagnosed with probable MSA were enrolled in this cross-sectional study. The diagnosis of RBD was based on the results of video polysomnography (PSG) and a history of abnormal sleep-related behaviors. The patients were divided into two groups: those with RBD and those without. These two groups were then compared in terms of severity of motor symptoms (Unified Multiple System Arophy Rating Scale) and non-motor symptoms (Non-Motor Symptoms Scale, Mini-Mental State Examination score, Epworth Sleepiness Scale, Fatigue Severity Scale, Pittsburgh Sleep Quality Index, REM Sleep Behavior Disorder Screening Questionnaire, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale) and sleep parameters as recorded on PSG.

resultsOf the 55 patients (35 males), 18 (33%, 13 males) were diagnosed with RBD. Patients with or without RBD did not differ in demographic characteristics, clinical features, or sleep parameters based on PSG.

conclusionThere was no difference in motor and non-motor symptoms between MSA patients with or without RBD, indicating that the presence of RBD may not be significantly associated with the severity of motor or non-motor dysfunction in MSA.
