DNA methylation and epigenomic profiling post-mortem of human remain analogs (Sus scrofa) in southern Ontario, Canada.

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
Understanding the dynamics of DNA methylation (DNAm) post-mortem could support forensic applications, particularly the estimation of the post-mortem interval (PMI), age, and sex of remains. In this study, we investigated DNAm changes in pig carcasses (Sus scrofa) as analogs for human decomposition, while measuring the progression of decay. Genome-wide methylation arrays and ELISA assays were run on pig soft tissues collected post-mortem, alongside assessments of DNA integrity. Overall, DNA integrity and DNAm levels declined throughout the post-mortem period, with distinct seasonal differences. We established thresholds for estimating age and sex, referred to as epigenomic profiling, showing that key epigenetic markers retain predictive value post-mortem. Additionally, CpG sites that mapped to the Sus scrofa genome were selected to develop an ElasticNet model that integrated DNAm to estimate the PMI, highlighting the potential of DNAm as an investigative tool. In conclusion, this study is the first to demonstrate the utility of DNAm and epigenomic profiling in extended PMIs, and the first successful attempt to estimate both age and sex post-mortem from DNAm alone.
