Plasma miRNA Biomarker Signatures in Parkinsonian Syndromes.
Article in Molecular neurobiology, 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
Diagnosing atypical parkinsonian syndromes (APS) remains challenging due to overlapping clinical features and limited diagnostic tools. Brain-enriched microRNAs (miRNAs), which regulate neuronal development and function, are detectable in plasma and could serve as molecular biomarkers. This prospective study aimed to identify plasma brain-enriched miRNAs that can distinguish APS and elucidate affected molecular pathways. Reverse transcription-quantitative PCR (RT-qPCR) was performed on plasma samples from patients with idiopathic Parkinson's disease (iPD), multiple system atrophy (MSA), including the cerebellar subtype (MSA-C) and the parkinsonian subtype (MSA-P), progressive supranuclear palsy (PSP), and healthy controls. MiRNA expression analysis revealed distinct molecular fingerprints for each parkinsonian syndrome, with opposite trends between MSA and iPD compared to controls, suggesting distinct pathogenic mechanisms. Most dysregulated miRNAs clustered at chromosome (Chr)14q32 and shared binding sites for CREB1, CEBPB, and MAZ transcription factors. Pathway analysis revealed enrichment in prion diseases, Hippo signaling, TGF-beta signaling, and FoxO signaling pathways.
