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

Sleep disorders are common in neurodegenerative diseases such as Parkinson's disease (PD), multiple system atrophy (MSA), amyotrophic lateral sclerosis (ALS), hereditary ataxias, and Alzheimer's disease (AD). Type, frequency, and severity of sleep disturbances vary depending on each of these diseases. Cell loss of the brainstem nuclei that modulates respiration, and dysfunction of bulbar and diaphragmatic muscles increase the risk for sleep-disordered breathing (SDB) in MSA and ALS. The most relevant SDB in MSA is stridor, whereas in ALS nocturnal hypoventilation due to diaphragmatic weakness is the most common sleep breathing abnormality. Stridor and nocturnal hypoventilation are associated with reduced survival in MSA and ALS. In contrast, sleep apnea seems not to be more prevalent in PD than in the general population. In some PD patients, however, coincidental obstructive sleep apnea (OSA) can be the cause of excessive daytime sleepiness (EDS). SDB can also occur in some hereditary ataxias, such as stridor in spinocerebellar ataxia type 3 (Machado-Joseph disease). The presence of concomitant OSA in patients with AD can have deleterious effects on nocturnal sleep, may result in EDS, and might aggravate the cognitive deficits inherent to the disease. However, whether OSA is more frequent in patients with AD than in the general population is uncertain. Recognition of SDB in neurodegenerative disease is important because they are associated with significant morbidity and potential effective treatments are available.
