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

Eosinophils have long been recognized as terminal effector cells in type 2 immunity; however, emerging evidence positions them as central regulators of intestinal homeostasis, immune modulation, and tissue adaptation. This review provides a comprehensive overview of gastrointestinal eosinophils, integrating recent advances in their development, regulatory mechanisms, functional subsets, and pleiotropic roles across tissues. The developmental and homing pathways that guide eosinophils to the gut are first discussed, with an emphasis on niche-derived signals that control their survival and localization. The functional heterogeneity of intestinal eosinophils is then highlighted, revealing marked transcriptional and spatial diversification. The diverse functions of gut eosinophils are further summarized, including their contributions to pathogen defense, tissue repair, mutual regulation with the microbiota, anti-tumor, and interactions with immune cells. Finally, the cross-tissue orchestration of eosinophil behavior is examined, with a focus on the gut-immune axis. By synthesizing current knowledge, this review aims to present a holistic picture of gastrointestinal eosinophil biology and to inspire new perspectives for understanding and treating eosinophil-associated intestinal disorders.
