Diagnostic Reclassification From Parkinson's Disease to Multiple System Atrophy Based on Longitudinal Clinical and Imaging Findings: A Case Report.
Article in Cureus, 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
It is often challenging to differentiate Parkinson's disease (PD) from multiple system atrophy (MSA) - particularly, the parkinsonian subtype (MSA-P) - in the early disease stages because of overlapping clinical features. Here, we report the case of a 72-year-old man who was initially diagnosed with PD but whose diagnosis was later changed to MSA-P following the emergence of autonomic dysfunction and characteristic magnetic resonance imaging (MRI) findings. He presented with tremors, rigidity, bradykinesia, and postural instability, and dopamine transporter imaging demonstrated bilateral presynaptic dopaminergic dysfunction. Cardiac
