The Role of Dynamic DNA Methylation in Liver Transplant Rejection in Children.
Article in Transplantation direct, 2022. 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
Transcriptional regulation of liver transplant (LT) rejection may reveal novel predictive and therapeutic targets. The purpose of this article is to test the role of differential DNA methylation in children with biopsy-proven acute cellular rejection after LT. Methods: Paired peripheral blood DNA samples were obtained before and after LT from 17 children, including 4 rejectors (Rs) and 13 nonrejectors (NRs), and assayed with MethylC capture sequencing approach covering 5 million CpGs in immune-cell-specific regulatory elements. Differentially methylated CpGs (DMCs) were identified using generalized linear regression models adjusting for sex and age and merged into differentially methylated regions (DMRs) comprising 3 or more DMCs. Results: Contrasting Rs versus NRs, we identified 2238 DMCs in post-LT and 2620 DMCs in pre-LT samples, which clustered in 216 and 282 DMRs, respectively. DMCs associated with R were enriched in enhancers and depleted in promoters. Among DMRs, the proportion of hypomethylated DMRs increased from 61/282 (22%) in pre-LT to 103/216 (48%, Conclusions: Dynamic methylation in distal regulatory regions reveals known transplant-relevant MHC-dependent rejection pathways and identifies novel loci for future mechanistic evaluations in pediatric transplant subcohorts.
