Manifestations of different sleep disorders in patients with vascular parkinsonism and their impact on prognosis.
Article in American journal of translational research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the clinical manifestations of various sleep disorders in patients with vascular parkinsonism (VP) and analyze their impact on disease prognosis.
methodsA retrospective study was conducted on 125 VP patients. Sleep disorders were assessed using the Insomnia Severity Index, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Chalder Fatigue Scale, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Restless Legs Syndrome Severity Self-Rating Scale, REM sleep behavior disorder (RBD) Severity Questionnaire, and Idiopathic Hypersomnia Questionnaire. VP severity was evaluated using all four sections of the Unified Parkinson's Disease Rating Scale (UPDRS). Logistic regression analysis was employed to evaluate the independent impact of different sleep disorders on adverse prognosis in VP patients.
results64.0% of patients had at least one sleep disorder, with insomnia (44.0%), RBD (37.6%), and restless legs syndrome (28.0%) being the most common. Patients with RBD had significantly higher UPDRS Part I and Part IV scores (P < 0.01). Multivariate logistic regression analysis revealed that insomnia (OR = 4.489, 95% CI: 1.903-10.589) and RBD (OR = 4.318, 95% CI: 1.814-10.280) were independent risk factors for adverse prognosis within one year.
conclusionsVP patients have a high incidence of various sleep disorders, which are closely associated with specific motor and non-motor symptoms as well as disease prognosis. Among these, RBD and insomnia serve as important clinical indicators for predicting poor prognosis in VP patients. Early identification and intervention of these sleep disorders may help delay disease progression and improve patients' quality of life.
