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
Fumonisin B1 (FB1) is a prevalent mycotoxin in moldy grains and feeds, highly toxic to livestock and compromising product quality while threatening food safety. Poultry exhibit low susceptibility to FB1, but the underlying tolerance mechanisms remain unclear. Traditional 3D chicken intestinal organoid models cannot simulate direct interaction between the epithelial monolayer and FB1, limiting the study of FB1-chicken intestinal crosstalk. Here, we established a 2D chicken intestinal organoid monolayer model, derived from intestinal crypts of 18-day-old specific pathogen-free chicken embryos, to systematically explore poultry's resistance mechanisms against FB1. Using this model, we compared FB1-induced effects with those in a porcine intestinal epithelial cell model. Results showed that FB1 exposure did not reduce transepithelial electrical resistance, induce abnormal expression of tight junction genes, or cause significant fluctuations in inflammatory factor levels in chicken intestinal organoid monolayers. Mechanistically, FB1 enhances chicken intestinal stem cell function by activating the Wnt/β-catenin pathway, thereby promoting epithelial regeneration and renewal to increase FB1 resistance and decrease toxin sensitivity in chickens. This study reveals a strategy for enhancing FB1 tolerance in poultry by promoting intestinal stem cell function, providing a new perspective for developing mycotoxin prevention and control strategies.
