Association between regular physical activity and biomarker changes in early Parkinson's disease patients.

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
introductionPhysical activity benefits patients with Parkinson's disease (PD) and is assumed to possess disease-modifying potential. PD-related biomarkers, such as dopamine transporter (DAT) imaging and cerebrospinal fluid (CSF) α-synuclein (α-syn) and amyloid β (Aβ), correlate with disease severity and, to some extent, reflect disease progression and pathology. However, the association between regular physical activity and PD biomarker changes remains unknown. This study aimed to investigate the association between physical activity and longitudinal trajectories of PD biomarkers.
methodsThis retrospective study included 444 patients with a median follow-up time of 5 years from the Parkinson's Progression Markers Initiative cohort. Data collection included physical activity as scaled by the Physical Activity Scale for the Elderly questionnaire, dopamine transporter imaging, CSF assessment, and serum biomarkers. We analyzed the data using a linear mixed regression model.
resultsRegular physical activity was associated with a slower decline of DAT uptake in the caudate (β = 0.063, p = 0.011) and the putamen (β = 0.062, p = 0.023). No association was detected between regular physical activity and CSF, as well as serum biomarkers.
conclusionRegular physical activity is associated with favorable PD biomarker progression, indicating a potential disease-modifying effect.
