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

Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) may occur at least 10 years before a clinical diagnosis of an α-synucleinopathy, such as dementia with Lewy bodies (DLB), Parkinson's disease (PD) or multiple system atrophy (MSA). The extent to which people with iRBD manifest subtle features of these conditions is an area of active research and whether these changes can be measured remotely in the community is an important aim. Better characterisation may aid early detection and monitoring for people at risk of neurodegeneration. The aim of this study was to investigate remote tests of subjective and objective features of α-synuclein-related conditions in probable iRBD (pRBD). We hypothesised that α-synuclein-related symptoms and signs would be more frequent in pRBD than healthy controls. 2,891 participants aged 50 + from the Tasmanian ISLAND Sleep Study completed the REM Sleep Behavior Disorder Single-Question Screen (RBD1Q), and several online questionnaires and unsupervised objective assessments of motor, cognitive and olfactory function. People with pRBD (n = 267; mean (SD) age 63 (7.6) years; 53% female) reported more α-synuclein-related features than controls (n = 2,624; mean (SD) age 64 (7.7) years; 75% female), especially orthostatic intolerance, neuropathic pain, falls, olfactory impairment and hand motor dysfunction. These results show that people with pRBD exhibit a range of symptoms and signs of α-synuclein-related conditions that can be measured using remote (online and postal) assessment tools. Remote monitoring in the community may aid early detection of progression to DLB, PD and MSA and facilitate enrolment into clinical trials.
