Association between Physical Activity, Depression Severity and Parkinson's Symptoms in Older Adults with Parkinson's disease: A Cross-Sectional Study.
Article in Annals of geriatric medicine and research, 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
backgroundDepression significantly impacts Parkinson's disease (PD) motor function, non-motor symptoms, and quality of life. While physical activity (PA) is associated with improved PD symptoms, the relationship between depression severity, PA levels, and PD symptoms remains underexplored. This study examines the associations between depression severity, PA, and PD motor and non-motor symptoms using a large dataset from the Fox Insight study.
methodsThis cross-sectional study analyzed data from 3,445 individuals with PD completed the Geriatric Depression Scale-Short Form (GDS-S), the Physical Activity Scale for the Elderly (PASE), the Unified Parkinson's Disease Rating Scale Part 2 (UPDRS-2), and the Non-Motor Symptoms Questionnaire (NMSQ). Participants were categorized into four groups based on GDS-S scores: normal (0-4), mild (5-8), moderate (9-11), and severe (≥12). Kruskal-Wallis tests, Pearson correlations, and multiple linear regression analyses were conducted to assess associations between depression severity, PA, and PD symptoms.
resultsHigher depression severity was associated with worse motor (UPDRS-2; χ²=756.72, p<0.001) and non-motor (NMSQ; χ²=1072.13, p<0.001) symptoms and lower PA levels (PASE; χ²=396.24, p<0.001). Regression analysis showed that NMSQ (β=0.449, p<0.001), UPDRS-2 (β=0.212, p<0.001), and PASE (β=-0.171, p<0.001) significantly predicted depression severity.
conclusionDepression severity in PD is strongly linked to increased PD symptom. These findings highlight the importance of integrating PA interventions and mental health strategies into PD management to improve overall well-being.
