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

The small-intestinal epithelium must simultaneously enable functions that are spatially compartmentalized along the length of the organ: nutrient absorption and protection against environmental insults. Although regional differences within the intestine have been recognized for centuries, only now has a comprehensive framework emerged to define this organization at molecular, cellular and functional levels. In this Review, we highlight the epigenetic and transcriptional features of small-intestinal zonation across longitudinal and apical-basal axes, and we examine the molecular mechanisms that establish regional gene expression profiles in epithelial cells during development and that maintain these distinctions into adulthood. We integrate these molecular insights with physiological data to present a refined model of the functional landscape of nutrient absorption. Finally, we discuss gastrointestinal diseases that target specific intestinal regions, underscoring the importance of understanding local tissue environments within this highly regionalized organ.
