Relating movement behaviours and non-motor characteristics in people with Parkinson's disease: A compositional data analysis approach.
Trial report in Journal of Parkinson's disease, 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
BackgroundPeople with Parkinson's disease (PwPD) have unhealthier movement behaviours (less moderate-to-vigorous physical activity (MVPA) and more sedentary behaviour (SB)), than healthy older adults. Associations across movement patterns and non-motor characteristics are poorly understood.ObjectivesTo investigate associations between relative time spent in MVPA, light-intensity physical activities (LIPA) and SB, and non-motor characteristics among PwPD, and to investigate theoretical changes in non-motor characteristics when time in different movement behaviours is reallocated.MethodsBaseline data from 119 participants in the STEPS randomised controlled trial was used. Movement behaviours were measured by ActiGraph GT3X accelerometers. Compositional data analysis assessed relative time in MVPA, LIPA and SB. Linear regression assessed associations between MVPA, LIPA and SB and self-reported anxiety and depression (HADS), executive function (TMT IV), self-efficacy for exercise (S-ESES) and activities-specific balance confidence (ABC). Isotemporal substitution modelling investigated theoretical changes in outcomes when time in MVPA, LIPA and SB were reallocated.ResultsBetter executive function was associated with more relative time in MVPA and less in LIPA. Higher exercise-self-efficacy was associated with more relative time in MVPA and less in SB. Better balance confidence related to more relative time in MVPA. Reallocating time showed that losing 20 min MVPA had a worse theoretical impact for these outcomes than the benefit of gaining 20 min.ConclusionsThe observed relationships between MVPA and executive function, balance confidence, and exercise-self-efficacy suggests particular importance of maintaining MVPA in PwPD. These findings can be utilized clinically by communicating the importance of maintaining time in MVPA among PwPD.
