Pre-symptomatic Parkinson's disease blood test quantifying repetitive sequence motifs in transfer RNA fragments.
Article in Nature aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
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
Early, efficient Parkinson's disease (PD) tests may facilitate pre-symptomatic diagnosis and disease-modifying therapies. Here we report elevated levels of PD-specific transfer RNA fragments carrying a conserved sequence motif (RGTTCRA-tRFs) in the substantia nigra, cerebrospinal fluid and blood of patients with PD. A whole blood qPCR test detecting elevated RGTTCRA-tRFs and reduced mitochondrial-originated tRFs (MT-tRFs) segregated pre-symptomatic patients with PD from controls (area under the receiver operating characteristic curve (ROC-AUC) of 0.75 versus 0.71 based on traditional clinical scoring). Strengthening PD relevance, patients carrying PD-related mutations presented higher blood RGTTCRA-tRFs/MT-tRFs ratios than mutation-carrying non-symptomatic controls, and RGTTCRA-tRF levels decreased in patients' blood after deep brain stimulation. Furthermore, RGTTCRA-tRFs complementarity to ribosomal RNA and the translation-supporting LeuCAG3-tRF might aggravate PD via translational inhibition, as reflected by disrupted ribosomal association of RGTTCRA-tRFs in depolarized neuroblastoma cells. Our findings show tRF involvement in PD and suggest a potential simple and safe blood test that may aid clinicians in pre-symptomatic PD diagnosis after validation in larger independent cohorts.
