Eating Disorders and Parkinson's Disease - 1: Comorbidities, Neurobiology and Family History.
Article in medRxiv : the preprint server for health sciences, 2026. 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
Objective: In response to a clinical observation of an Anorexia Nervosa (AN) patient with family history of Parkinson's Disease (FHoPD), and evidence of similarities in dopamine function, personality, anxiety and weight loss symptoms between AN and PD, we completed a pilot study to estimate FHoPD in families of those with eating disorders (EDs). Method: We ascertained FHoPD among ED patients and community participants, and estimated relative risks (RRs) for AN, Bulimia Nervosa (BN) and Binge Eating Disorder (BED). Results: We observed increased FHoPD among patients and community participants (N=482) meeting criteria for ED diagnoses compared to community participants (N=394) without an ED diagnosis. For AN, FHoPD prevalence was 6.6% vs 3.4%, χ Conclusions: EDs are associated with an elevated FHoPD. Translational analyses leveraging disorder-specific research resources may benefit our understanding of the genetics and neuroscience of both disorders.
