Cell-Free DNA and Mitochondria in Parkinson's Disease.
Review in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Parkinson's disease (PD) is a progressive neurodegenerative disorder marked by the gradual and irreversible loss of neurons, especially within the substantia nigra region of the midbrain. Early and accurate diagnosis remains a significant challenge in both research and clinical practice. This difficulty is further compounded by the substantial clinical and molecular heterogeneity of PD, emphasizing the urgent need for reliable biomarkers to enhance diagnostic precision and guide therapeutic strategies. One promising candidate biomarker is cell-free DNA (cfDNA), comprising short DNA fragments composed of mitochondrial (cf-mtDNA) and nucleus-derived (cf-ntDNA) DNA. cfDNA is released into body fluids through physiological or pathological processes such as apoptosis, necrosis, NETosis, or active secretion. The presence of cfDNA in human biological fluids has been utilized for years in oncology and prenatal medicine and, more recently, it has gained attention as a non-invasive diagnostic tool in the context of neurodegenerative diseases such as PD. This review article aims to provide a comprehensive overview of the current knowledge on the origin of cfDNA, highlighting the roles of the mitochondria and cf-mtDNA in PD, mitochondria quality control, and neuroinflammation in cfDNA biogenesis. The review collates available research on cfDNA types in human serum, plasma, and CSF, sequence analysis, and its potential application as a biomarker in the diagnosis and monitoring of PD, contributing to the ongoing search for non-invasive biomarkers of neurodegenerative diseases.
