Mitoepigenetic Alterations in Early-Onset Parkinson's Disease.
Article in International journal of molecular 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
There is accumulating evidence that distinct mitochondrial DNA (mtDNA) methylation and hydroxymethylation patterns exist in Parkinson's disease (PD). However, most studies have been limited to the investigation of specific target regions, rather than the entire mtDNA, and have been further hindered by other methodological discrepancies and the lack of non-CpG context investigation. Here, we provide a comprehensive profile of methylation and hydroxymethylation levels across the mitochondrial genome, at global and single-base resolution, in CpG and non-CpG (CHG, CHH) contexts in blood samples from early-onset PD (EOPD) patients (n = 39) and age- and sex-matched controls (n = 63). Bisulfite (BS) and oxidative-bisulfite (oxBS) conversions in parallel workflows followed by next-generation sequencing (NGS) using Illumina's Novaseq 6000 sequencing system identified mitochondrial 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) in all contexts. Global mtDNA methylation was significantly higher in EOPD patients vs. matched controls in the CpG context (
