1 · What the graph read from it

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.

2 · The registry

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

Group 3 innate lymphoid cells (ILC3) are crucial in neonatal necrotizing enterocolitis (NEC); however, the underlying mechanisms remain elusive. Here, we identify NKp46⁻CCR6⁻ (double-negative, DN) ILC3s as the dominant pathogenic subset driving NEC via IL-17 A secretion, which disrupts intestinal barrier integrity. Mechanistically, Atg5 activates autophagy in DN ILC3s during NEC. Atg5 conditional knockout in RORγt⁺ cells mitigates NEC, reduces DN ILC3 accumulation and IL-17 A production. Atg5 deficiency also decreases HIF-1α chromatin accessibility and transcriptional activity, shifting DN ILC3 metabolism from glycolysis to fatty acid oxidation. Lipidomics reveals phosphatidylcholine as a key downstream metabolite of Atg5-mediated autophagy. Phosphatidylcholine supplementation suppresses DN ILC3-driven inflammation, restores metabolic homeostasis, elevates Clostridium abundance, and ameliorates NEC in mice. Importantly, human NEC tissues exhibit increased ILC3 proportions, autophagic activity, and IL-17 A/IL-22 secretion. Thus, we uncover an Atg5-autophagy-glycolipid metabolic axis in DN ILC3s that drives NEC pathogenesis, providing a promising therapeutic target for neonatal NEC.
