Association between motor symptom severity and urinary dysfunction in Parkinson's disease: a retrospective study.
Article in Frontiers in aging neuroscience, 2025. 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
Introduction: Urinary dysfunction is a common non-motor symptom in patients with Parkinson's disease (PD) and is often associated with greater motor disability and reduced quality of life. Despite its clinical relevance, the association between motor symptom severity and urinary dysfunction remains poorly understood. This study aimed to elucidate this relationship using validated clinical questionnaires to assess urinary symptoms. Methods: We conducted a single-center, retrospective cross-sectional study including 223 patients with PD who visited a university hospital between September 2023 and February 2024. Urinary dysfunction was evaluated using the Overactive Bladder Symptom Score (OABSS) and International Prostate Symptom Score (IPSS), comprising the symptom (IPSS-symptom score; Q1-7) and satisfaction (IPSS-satisfaction score; Q8) scores. We analyzed the changes in urinary symptoms, overall satisfaction, and prodromal symptoms across the Hoehn and Yahr (HY) stages. Patients were divided into early (HY ≤ 2) and late (HY > 2) groups to assess early urinary symptom changes. Results: The OABSS, IPSS-symptom score, and IPSS-satisfaction score significantly increased with advancing HY stage. Compared to the early group, the late group exhibited significantly higher OABSS ( Conclusion: Our study provides evidence that urinary dysfunction intensifies with motor symptom progression in PD. These findings highlight the importance of early detection and proactive management of urinary symptoms in patients with PD to enhance their overall quality of life.
