Progressive Pontine-Medullary Dysfunction Leads to REM Sleep Behavior Disorder Symptoms in a Chronic Model of Parkinson's Disease.
Article in Nature and science of sleep, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundClinical observations reveal that rapid eye movement (REM) sleep behavior disorder (RBD) often develops prior to alpha-synucleinopathies including Parkinson's disease (PD). However, a causal relationship between alpha-synucleinopathy and Parkinsonian neurodegeneration has not been delineated.
methodsRats were chronically treated with rotenone and EEG and EMG signals were recorded for analysis of sleep behavior, assisted by video recording of body movements. C-fos expression and TUNEL staining were used to assess neuronal activation and apoptosis, respectively. Chemogenetic manipulation of brain stem nuclei was conducted to ameliorate RBD symptoms in rotenone-treated rats.
resultsRats chronically exposed to rotenone exhibited progressive RBD features, from EEG slowing to REM sleep motor behavior and NREM muscle activities. Temporally, these phenomena correlated well with progressive alpha-synuclein aggregation and neuronal apoptosis in the sublaterodorsal tegmental nucleus (SLD) and gigantocellular ventricular reticular nucleus in the brainstem. Chemogenetic activation of glutamatergic neurons in SLD alleviated RBD symptoms in the rotenone model.
conclusionTaken together, these results are consistent with a progressive degeneration in the REM sleep promoting and atonia circuit in early Parkinsonism that underlies the emergence of RBD symptoms, and demonstrate that the rotenone model is useful for further studies into RBD and its relationship to PD.
