Epigenetic changes associated with severe necrosis and survival in preterm infants with surgical necrotizing enterocolitis.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundWe aim to determine the epigenetic changes assessed by DNA methylation associated with necrosis severity and survival in preterm infants with surgical necrotizing enterocolitis (NEC).
methodsUsing Illumina's Infinium EPIC v2.0 BeadChips, the DNA methylation profiles of 46 infants with NEC were generated from intestinal tissue collected during laparotomy. Samples were categorized by disease severity and survival outcome. STRING functional enrichment analyses and MCODE network analyses of the genes found to contain CpG sites with significantly different methylation levels (Benjamini-Hochberg adjusted p-value ≤ 0.01) were used to investigate the biological relevance of the epigenetic differences between sample groups.
results4570 CpG sites showed a significant difference in methylation when comparing survivors (n = 34) and non-survivors (n = 12) of surgical NEC (p < 0.05). 19,518 CpG sites showed a significant difference in methylation when comparing NEC patients with low (n = 18) and high necrosis (n = 28) (p < 0.05). Genes with the greatest number of significant methylation sites include PRDM16, SEPTIN9, FOXP1, POLR1C, and several homeobox genes. NOTCH and Rap1 signaling were two of the major pathways identified.
conclusionThe DNA methylation profiles of infants with surgical NEC were found to differ, depending on necrosis severity and survival outcome. IMPACT: The DNA methylation profiles in surgical necrotizing enterocolitis (NEC) were found to differ depending on necrosis severity and survival outcome. Significant differences in the DNA methylation levels of thousands of genes helped identify molecular pathways that may be epigenetically regulated and involved in disease progression. These genes and molecular pathways are potential therapeutic targets for NEC, an incompletely understood and life-threatening disease.
