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

background and purposeTo investigate the association between sleep hygiene practices and sleep disturbance in patients with Parkinson's disease (PD).

methodsA cross-sectional study was conducted involving 109 PD patients. Sleep disturbance and sleep hygiene were evaluated using the Korean version of Parkinson's Disease Sleep Scale-2 (K-PDSS-2) and the Sleep Hygiene Practice Scale-Korean version (SHPS-K), respectively. Multivariate linear regression analysis was performed, adjusting for potential confounding factors, such as age, body mass index, education, Hoehn and Yahr stage, cognitive function and depressive symptoms.

resultsHigher SHPS-K scores, reflecting poorer sleep hygiene, were significantly associated with greater sleep disturbance (B=0.254,

conclusionsPoor sleep hygiene is significantly associated with disturbed sleep in patients with early-stage PD. These findings support the potential utility of non-pharmacological interventions targeting modifiable behavioral factors to improve sleep-related outcomes in patients with PD.
