Parkinson's disease-associated alterations in DNA methylation and hydroxymethylation in human brain.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Epigenetic mechanisms mediate interactions between aging, genetics, and environmental factors in sporadic Parkinson's disease (PD). While multiple studies have explored DNA modifications in PD, few focus on 5-hydroxymethylcytosine (5hmc), which is important in the central nervous system and sensitive to environmental exposures. Existing studies have not differentiated between 5-methylcytosine (5mc) and 5hmc or have analyzed them separately. In this study, we modeled 5mc and 5hmc data simultaneously. We identified 108 cytosines with significant PD-associated shifts between these marks in an enriched neuronal population from PD postmortem parietal cortex, within 83 genes and 34 enhancers associated with 67 genes. These data potentially link epigenetic regulation of genes related to LRRK2 and endolysosomal sorting (RAB32 and AGAP1), and genes involved in neuroinflammation, the inflammasome, and neurodevelopment with early changes in PD and suggest that there are significant shifts between 5mC and 5hmC associated with PD in genes not captured by standard methods.
