Obesity and the development of Parkinson's disease within the Framingham Heart study cohort.
Article in Clinical parkinsonism & related disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Objective: To determine the role of obesity in the development of Parkinson's disease (PD). Background: Obesity has been reported to be both a risk factor for PD, as well as potentially protective. The Framingham Heart Study (FHS) is a multigenerational longitudinal cohort study that was started in 1948, which is well-known for its cardiovascular health studies. In this study, we utilized the extensive cardiovascular and neurological data to determine if obesity contributes to the risk of the development of PD. Methods: Participants in the FHS Original and Offspring cohorts were included in this study. Controls were selected based on sex and age at baseline examination, 1:10. Cox proportional hazard regression models were used, adjusting for age and sex. PD case status was determined utilizing prior medical and neurological examination data, Framingham Heart Study examinations, and self-report data by a panel of movement disorders neurologists using the UK Brain Bank Criteria (UKBB) and other supporting clinical details after being flagged for review by FHS neurologists. We used p < 0.05 for significance. Results: Accounting for missing covariate data, this study included 117 participants with PD, with 1170 controls. We found that higher BMI was associated with lower PD risk, with participants with BMI 25 kg/m2 to 30 kg/m2 having HR of 0.66 (CI 0.44-0.98; p = 0.04) and BMI >= 30 kg/m2 having HR 0.47 (CI 0.27-0.84; p = 0.01). When the overweight and obese BMI groups were combined, we noted a more robust association, with combined HR of 0.67 (0.41-0.86; p = 0.01). Conclusions: Obesity during mid-life potentially reduces the risk of developing PD; however, additional studies are needed to further explore this association.
