Threonine attenuates lipopolysaccharide-induced intestinal inflammatory responses in rabbits.
Article in European journal of nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeThreonine (Thr) can be involved in the synthesis of immunoglobulins, which play the role of immune regulation, Thr also has to improve intestinal morphology, adjust the sticky protein synthesis, maintain the intestinal barrier function, etc. The experiment aimed to investigate the effects of diets supplemented with different levels of Thr on growth performance and intestinal health of rabbits under lipopolysaccharide (LPS) stress conditions.
methodsA total of 180 healthy 35-day-old weaned New Zealand White rabbits were randomly assigned in a 2 × 3 factorial design to receive an intraperitoneal injection of 100 µg/kg BW LPS or saline and three diets with different levels of digestible threonine (0.43%, 0.54%, and 0.64%).
resultsThe LPS challenge resulted in a reduction in body weight in rabbits at day 22, as well as a decrease in the serum d-lactic acid (D-LA) content and the number of goblet cells (GCs) in the jejunum. Additionally, the duodenum JAM2 and JAM3 were down-regulated. The expression of OCLN, ZO-1, and IL-2 in the jejunum, and CLDN, nuclear factor-κB (NF-κB) and ZO-1 mRNA in the ileum were also down-regulated. Furthermore, the duodenum TLR4 and IL-1β mRNA expression, while the jejunum exhibited an elevation in CLDN, TNF-α, and ileum TNF-α mRNA expression (P < 0.05). In the context of LPS challenge condition, dietary Thr addition was found to down-regulate the duodenum ZO-1 and jejunum CLDN mRNA expression of rabbits (P < 0.05). This was accompanied by an increase in ileum sIgA content and GCs number (P < 0.05). Additionally, dietary Thr addition resulted in a downregulation of duodenum TLR4, MyD88, NF-κB, TNF-α and IL-1β, jejunum MyD88, and IL-1β mRNA expression, as well as an up-regulation of ileum IL-10 mRNA expression in rabbits (P < 0.05).
conclusionIn conclusion, the LPS challenge can result in intestinal inflammation and damage the integrity of the intestinal barrier in rabbits. Nevertheless, dietary Thr supplementation can alleviate the intestinal inflammatory response in rabbits challenged with LPS.
