Lower Urinary Tract Symptoms Correlation With Motor and Cognitive Function in Patients With Parkinson Disease.
Article in International neurourology journal, 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
purposeParkinson disease (PD) is a common, progressive neurodegenerative disease, affecting approximately 1% of the population over 60. The associated morbidity and mortality are increasing at a faster rate than for any other neurological disorder. Lower urinary tract symptoms (LUTS) are reported in up to 85% of patients and can significantly impair quality of life (QoL). There are few studies to date that utilise the Montreal Cognitive Assessment (MoCA) to assess cognitive performance and compare this to motor symptoms and LUTS severity.
methodsAn observational, cross-sectional study was performed. Data was collected prospectively from patients diagnosed with PD attending a specialist movement disorder clinic using fully validated, detailed questionnaires and scales routinely employed in clinical practice (ICIQ-MLUTS, ICIQ-FLUTS, Unified PD Rating Scale - Motor Examination, modified Hoehn and Yahr, MoCA). Statistical analyses were performed using Stata/MP 17.
resultsData from 18 patients was collected (15 male and 3 female subjects; median age, 69 years; median disease duration, 4 years; median modified Hoehn and Yahr stage, 2.5; median MoCA score, 24). Urinary incontinence symptoms scores were significantly correlated with worse QoL scores due to LUTS (r=0.76, P<0.001), with total urinary symptoms scores (r=0.82, P<0.001), and negatively correlated with MoCA scores (r=-0.52, P=0.046). No correlation was found between urinary incontinence symptoms and motor symptoms severity scores (r=0.09, P=0.725). The non-drug-naive group (n=12, 66.7%) was found to have higher motor symptoms scores (P=0.065), higher LUTS scores (P=0.239), worse QoL scores due to LUTS (P=0.244), and similar MoCA scores (P=0.785) to the drug-naive group (n=6, 33.3%).
conclusionCognitive impairment in patients with PD appears to be more strongly associated with urinary incontinence severity than motor symptoms. When considering the appropriateness of urological intervention in PD patients, cognitive function should be taken into account as well as motor function.
