Sleep quality in Parkinson disease: an examination of clinical variables.

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
The etiology of sleep problems in Parkinson disease (PD) is not well understood, as they may arise from the pathology of the disease or from other disease-related factors such as motor dysfunction, dopaminergic medication, and mood disturbances. The aim of this study was to investigate factors associated with sleep, including disease-related variables such as motor symptom severity, dose of medication, and mood and disease subtypes. Thirty-five nondemented patients with PD were included. Sleep was measured using 24-hour wrist actigraphy over a 7-day period, during which time participants kept a sleep diary. Subjective sleep and arousal questionnaires included the PD Sleep Scale and Epworth Sleepiness Scale. Motor symptom severity and dopaminergic medication were significantly related to measures of sleep quality. Sex differences in sleep quality were found, with men having worse sleep quality and more excessive daytime sleepiness than women. We also found that actigraphy may serve as a useful tool for identifying individuals with possible rapid eye movement behavior disorder, a sleep disorder that has important implications in early detection of PD.
